The self-charging concept has drawn considerable attention due to its excellent ability to achieve environmental energy harvesting,conversion and storage without an external power supply.However,most self-charging designs assembled by multiple energy harvesting,conversion and storage materials increase the energy transfer loss;the environmental energy supply is generally limited by climate and meteorological conditions,hindering the potential application of these selfpowered devices to be available at all times.Based on aerobic autoxidation of catechol,which is similar to the electrochemical oxidation of the catechol groups on the carbon materials under an electrical charge,we proposed an air-breathing chemical self-charge concept based on the aerobic autoxidation of catechol groups on oxygen-enriched carbon materials to ortho-quinone groups.Energy harvesting,conversion and storage functions could be integrated on a single carbon material to avoid the energy transfer loss among the different materials.Moreover,the assembled Cu/oxygen-enriched carbon battery confirmed the feasibility of the air-oxidation self-charging/electrical discharging mechanism for potential applications.This air-breathing chemical self-charge concept could facilitate the exploration of high-efficiency sustainable air self-charging devices.

Porous aromatic framework 1(PAF-1)is an extremely representative nanoporous organic framework owing to its high stability and exceptionally high surface area.Currently,the synthesis of PAF-1 is catalyzed by the Ni(COD)2/COD/bpy system,suffering from great instability and high cost.Herein,we developed an in situ reduction of the Ni(II)catalytic system to synthesize PAF-1 in low cost and high yield.The active Ni(0)species produced from the NiCl_(2)/bpy/NaI/Mg catalyst system can effectively catalyze homocoupling of tetrakis(4-bromophenyl)methane at the room temperature to form PAF-1 with high Brunauer-Emmett-Teller(BET)-specific surface area up to 4948 m^(2) g^(−1)(Langmuir surface area,6785 m2 g−1).The possible halogen exchange and dehalogenation coupling mechanisms for this new catalytic process in PAF's synthesis are discussed in detail.The efficiency and universality of this innovative catalyst system have also been demonstrated in other PAFs'synthesis.This work provides a cheap,facile,and efficient method for scalable synthesis of PAFs and explores their application for high-pressure storage of Xe and Kr.

Chemical Research in Chinese Universities 2024年第1期40卷 109-118页

作者： ZHANG Wanjia GUO Tingyu LIU Yanhua ZHANG Xuewei ZOU Bo ZHAO Chun SUO Hui WANG Hui ZHAO Xu College of Chemistry Jilin UniversityChangchun130012P.R.China State Key Laboratory of Integrated Optoelectronics College of Electronic Science and EngineeringJilin UniversityChangchun130012P.R.China Department of Chemical and Biological Engineering University of SaskatchewanSaskatoonSKS7N 5A9Canada

A composite material comprising a carbon layer and spherical carbon/carbon cloth(C-SC/CC)was fabricated using a hydrothermal-pyrolysis method,employing carbon cloth as the substrate and glucose as the carbon source.The C-SC/CC electrode was evaluated as an electrocatalytic electrode for hydrogen production by electrolysis of Bunsen reaction products.The electrode prepared with 4 g of glucose and annealed at 800°C showed excellent electrocatalytic activity.It requires only a potential of 185 mV(vs.SCE)to achieve a current density of 10 mA/cm2.Furthermore,the electrode demonstrated good stability with a 6%loss in current density after 1000 cycles of scanning from 0.2 V to 1.2 V.These results indicate the potential of the SC/CC electrode as an efficient and durable electrocatalyst for the electrolysis of H2SO4 and HI.

Dye-sensitized solar cells(DSSCs) have attracted great attention because of their simplicity,low-cost,and environmentally friendly.The counter electrode(CE) is an important part of the DSSCs,and the function of CE is to catalyze the iodine/iodide(I/I) redox couple and complete the electric circuit in DSSCs.However,the scarcity and high price of noble metal Pt severely restrict its use in the development of DSSCs.In contrast,carbon materials derived from biomass have aroused great concern due to their inexpensive,abundant and superior electrocatalytic activity.A novel carbon material is used in DSSCs in this work,and obtain a higher power conversion efficiency of 5.30%.On the other hand,the as-prepared carbon material as an accelerant in anaerobic digestion(AD) also achieve high cumulative biogas yield(460.8 m L/g VS) and chemical oxygen demand removal rate(56.7%).The application of carbon materials in DSSC and AD provides a new reference for solving the energy crisis.

Powder metallurgy is important in material preparation.Due to the inertness of carbon materials,however,sintering powdered carbon into physically coherent bulks has been a great challenge even at a high temperature(2000).Improving the sintering activity of carbon powders is℃the key to the success of the consolidation of the carbon powders.Here ordered mesoporous carbon(OMC)is used as the starting material to produce highly homogeneous novel carbon bulks.During sintering at 1800,the huge specific surface area of the OMC greatly promotes the migration of℃carbon atoms and thus the sintering of the OMC by surface diffusion mechanism.When nanodiamond(ND)is added,the volume expansion associated with the phase transformation of diamond to graphite facilitates the densification of the powder compacts.The strong connection between the OMC and the graphite onions derived from the ND bestows the as-prepared carbon bulks with excellent mechanical properties.The current research pioneers a novel way to prepare high-strength carbon materials at relatively low temperatures.

This study presents an overview on graphene synthesis,fabrication and different characterization techniques utilized in the production.Since its discovery in 2004 by Andre Geim and Kostya Novoselov several research articles have been published globally to this effect,owing to graphene’s extraordinary,and exclusive characteristics which include optical transparency,excellent thermal,and mechanical properties.The properties and applications of this two-dimensional carbon crystal composed of single-layered material have created new avenues for the development of high-performance future electronics and technologies in energy storage and conversion for the sustainable energy.However,despite its potential and current status globally the difficulty in the production of monolayer graphene sheet still persists.Therefore,this review highlighted two approaches in the synthesis of graphene,which are the top-down and bottom-up approaches and examined the advantages and failings of the methods involved.In addition,the prospects and failings of these methods are investigated,as they are essential in optimizing the production method of graphene vital for expanding the yield,and producing high-quality graphene.

Integrating the merits of long lifespan and excellent energy as well as power densities,potassium-ion hybrid capacitors(PIHCs)exhibit great prospects for future energy storage devices.To boost comprehensive performance of PIHCs,heteroatom-doping and morphology-tuning as two comprehensive strategies have been devoted to designing uniquely structural carbon-based materials with favorable advantages.An ideal strategy for simultaneous atomic doping and structural regulation is expected to be developed.Herein,we propose a novel"Killing Two Birds with One Stone"strategy to prepare a tri-elements doped hollow carbon sphere(TED-HCS)as PIHCs anodes,that is,a single template of spherical CoP particles is rationally adopted,which not only provides both a P source for heteroatom-doping but also acts as a selfsacrificial template for hollow-structure engineering.The multifunctional TED-HCS presents a high capacity of 473.0 mAh g^(-1) and excellent rate performance of 212.5 mAh g^(-1) at 5.0 A g^(-1).Remarkably,the as-assembled PIHCs show outstanding energy/power density(40.4 Wh kg^(-1)/10500 W kg^(-1))and remain high-capacity retention of 89.15%even cycling 12,000 times.The"Killing Two Birds with One Stone"strategy offers new insight into the search for the preparation of carbon-based materials with multi-elements doping and specific morphology structure.

The realization of“carbon peak”and“carbon neutralization”highly depends on the efficient utilization of renewable energy sources.Exploring reliable and low-cost electrochemical energy storage systems is an ever-growing demand for renewable energy integration.Among available candidates,aqueous zinc-ion batteries(AZIBs)receive extensive researchers'attention because of their material abundance,high capacity,high safety,and environmental friendliness.However,the irreversible issues of Zn anode in terms of notorious dendric Zn growth,Zn corrosion/hydrogen evolution,and passivation significantly impede the commercialization of high-performance AZIBs.carbon materials have advantages of large specific surface area,low cost,high electrical conductivity,controllable structure,and good stability.Their application provides remedies for improving the comprehensive performance of Zn anodes.In this review,the fundamentals and issues of Zn anodes,and the research progress with functional carbon materials for Zn anodes in recent years are presented.Three major strategies are described in detail,including the use of carbon materials(carbon nanotubes,graphene,carbon fiber,metal-organic framework(MOF)derived host,etc.)as Zn plating/stripping substrates,as protective coating layers on Zn,and as electrolyte additives.Finally,the remaining challenges and perspectives of carbon materials in high-performance AZIBs are outlined.

Synthesis of hybrid carbon materials with core-shell structure and robust catalytic performance is of great research interest,and remains a great challenge in catalytic dehydrogenation of hydrocarbons reaction.In this paper,few-layer sp^(2) carbon decorated SiC nanocrystals with core-shell structure(SiC@C)were fabricated through a dual-confined magnesiothermic method by employing glucose and SiO_(2) as precursors.The SiC@C nanocrystals were further crosslinked to be a three dimensional(3D)mesoporous hybrid by the in situ generated carbon as binders and exhibiting a 410.30 m^(2) g^(−1) large surface area.The as-prepared SiC@C hybrid materials as metal-free catalysts were evaluated in the steam-free direct dehydrogenation of ethylbenzene to styrene.Benefiting from the abundant surface carbonyl groups on the graphite carbon layers,the optimized yield rate of styrene normalized by carbon mass was as high as 11.58 mmol g^(−1) carbon h^(−1),nearly 4 times that of nanodiamonds.Considering the low cost and excellent catalytic activity,the hybrid 3D SiC@C material may be a promising candidate for direct dehydrogenation of hydrocarbons.

Activating MoS_(2) with atomic metal doping is promising to harvest desirable Pt-matched hydrogen evolution reaction(HER)catalytic performance.Herein,we developed an efficient method to access edgerich lattice-distorted MoS_(2) for highly efficient HER via in-situ sulphuration of atomic Co/Mo species that were well-dispersed in a formamide-derived N-doped carbonaceous(f-NC)substrate.Apart from others,pre-embedding Co/Mo species in f-NC controls the release of metal sources upon annealing in S vapor,grafting the as-made MoS_(2) with merits of short-range crystallinity,distorted lattices,rich defects,and more edges exposed.The content of atomic Co species embedded in MoS_(2) reaches up to 2.85 at.%,and its atomic dispersion has been systematically confirmed by using XRD,HRTEM,XPS,and XAS characterizations.The Co-doped MoS_(2) sample exhibits excellent HER activity,achieving overpotentials of 67 and155 m V at j=10 m A cm^(-2) in 1.0 M KOH and 0.5 M H_(2)SO_(4),respectively.Density functional theory simulations suggest that,compared with free-doping MoS_(2),the edged Co doping is responsible for the significantly improved HER activity.Our method,in addition to providing reliable Pt-matched HER catalysts,may also inspire the general synthesis of edge-rich metal-doped metal chalcogenide for a wide range of energy conversion applications.
