Tremendous efforts have been dedicated to developing high-performance energy storage devices based on the micro-or nano-manipulation of novel carbon electrodes, as certain nanocarbons are perceived to have advantages such as high specific surface areas, superior electric conductivities, excellent mechanical properties and so on. In typical electrochemical electrodes, ions are intercalated/deintercalated into/from the bulk(for batteries) or adsorbed/desorbed on/from the surface(for electrochemical capacitors). Fast ionic transport, significantly determined by ionic channels in active electrodes or supporting materials, is a prerequisite for the efficient energy storage with carbons. In this report, we summarize recent design strategies for ionic channels in novel carbons and give comments on the promising features based on those carbons towards tailorable ionic channels.

随着电磁波(EMW)污染的日益严重,开发高性能电磁波吸收材料(EWAMs)已成为研究热点.碳基EWAMs具有优异的物理、化学稳定性和高导电性带来的强介电损耗.特别是三维(3D)多孔碳基EWAMs在EMW吸收研究领域长盛不衰.3D多孔结构大大降低了材料的密度,有利于EMW的多次反射和散射,优化了阻抗匹配,因此有望实现“低密度、薄厚度、宽吸收带宽、强吸收”的目标.在此,我们首先阐明了相关的理论基础和评价方法.之后,我们以材料来源为主线索,总结了3D多孔碳基EWAMs的最新研究进展,并突出了其中一些独特而新颖的观点.最后,提出了3D多孔碳基EWAMs的挑战和前景,这将有助于高性能EWAMs的进一步发展.

An ideal type-Ⅲnodal point is generated by crossing a completely flat band and a dispersive band along a certain momentum direction.To date,the type-Ⅲnodal points found in two-dimensional(2D)materials have been mostly accidental and random rather than ideal cases,and no one mentions what kind of lattice can produce ideal nodal points.Here,we propose that ideal type-Ⅲnodal points can be obtained in a diamond-like lattice.The flat bands in the lattice originate from destructive interference of wavefunctions,and thus are intrinsic and robust.Moreover,the specific lattice can be realized in some 2D carbon networks,such as T-graphene and its derivatives.All the carbon structures possess type-ⅢDirac points.In two of the structures,consisting of triangular carbon rings,the type-ⅢDirac points are located just on the Fermi level and the Fermi surface is very clean.Our research not only opens a door to finding the ideal type-ⅢDirac points,but also provides 2D materials for exploring their physical properties experimentally.

materials with appropriate adhesive properties are suitable for the fabrication of bionic adhesive pads. In this study, a novel polydimethylsiloxane （PDMS） material enhanced with two types of crosslinkers, carbon nanotubes and graphene sheets, was fabricated. The Contact Angle （CA） and cross-sectional morphology of the new material were investigated and observed using a CA meter and Scanning Electron Microscopy （SEM）, respectively. CA measurements indicate that the surface energy of the novel material is twice that of the common PDMS material. SEM observations show that carbon nanotubes and graphene sheets are well dispersed in the polymer, a feature that improves the mechanical properties of the new material. The adhesive performance of this novel composite was tested on an in-house fabricated friction machine. Results show that at a preload of only 50 mN, the adhesion of the novel PDMS material is up to -3.7 times that of common PDMS. The maximum macroscale shear strength and normal adhesion reach 4 N·cm^-2 and 1 N·cm^-2, respectively. The adhesive capability of the material is maintained even after hundreds of times of repeated use. This novel material exhibits excellent adhesion, sufficiently high elastic modulus and high repeatability at low preloads.

Design of supportive atomic sites with a controllably adjusted coordinating environment is essential to advancing the reduction of CO_(2) to value-added fuels and chemicals and to achieving carbon neutralization.Herein,atomic Ni(Zn)sites that are uniquely coordinated with ternary Zn(Ni)/N/O ligands were successfully decorated on formamide-derived porous carbon nanomaterials,possibly forming an atomic structure of Ni(N_(2)O_(1))-Zn(N_(2)O_(1)),as studied by combining X-ray photoelectron spectroscopy and X-ray absorption spectroscopy.With the mediation of additional O coordination,the Ni-Zn dual site induces significantly decreased desorption of molecular CO.The NiZn-NC decorated with rich Ni(N_(2)O_(1))-Zn(N_(2)O_(1))sites remarkably gained>97%CO Faraday efficiency over a wide potential range of -0.8 to -1.1 V(relative to reversible hydrogen electrode).Density functional theory computations suggest that the N/O dual coordination effectively modulates the electronic structure of the Ni-Zn duplex and optimizes the adsorption and conversion properties of CO_(2) and subsequent intermediates.Different from the conventional pathway of using Ni as the active site in the Ni-Zn duplex,it is found that the Ni-neighboring Zn sites in the Ni(N_(2)O_(1))-Zn(N_(2)O_(1))coordination showed much lower energy barriers of the CO_(2) protonation step and the subsequent dehydroxylation step.

Secondary batteries are widely used in energy storage equipment.To obtain high-performance batteries,the development and utilization of electrode materials with cheap price and ideal theoretical gravimetric and volumetric specific capacities have become particularly important.Naturally abundant and low-cost red phosphorus(RP)is recognized as an anode material with great promise because it has a theoretical capacity of 2596 mA h g^(-1) in lithium-ion batteries(LIBs)and sodium-ion batteries(SIBs).However,owing to the inferior discharging,the capacity of pure RP has a fast decay.Nanoconfinement of RP nanoparticles within porous carbon framework is one of the efficient methods to overcome these problems.In this review,we introduce the recent progress of RP confinement into carbon matrix as an energy storage anode material in LIBs,SIBs and potassium-ion batteries(PIBs).The synthetic strategies,lithiation/sodia tion/potassiation mechanism,and the electrochemical performances of RP/carbon composites(RP/C)with kinds of designed structures and P-C and P-O-C bond by kinds of methods are included.Finally,the challenges and perspectives of RP faced in the application development as anodes for LIBs/SIBs/PIBs are covered.This review will strengthen the understanding of composites of RP nanoparticles in porous carbon materials and aid researchers to carry out future work rationally.

Confined nanospace pyrolysis(CNP)has attracted increasing attention as a general strategy to prepare task-specific hollow structured porous carbons(HSPCs)in the past decade.The unique advantages of the CNP strategy include its outstanding ability in control of the monodispersity,porosity and internal cavity of HSPCs.As a consequence,the obtained HSPCs perform exceptionally well in applications where a high dispersibility and tailored cavity are particularly required,such as drug delivery,energy storage,catalysis and so on.In this review,the fundamentals of the CNP strategy and its advances in structural alternation is first summarized,then typical applications are discussed by exemplifying specific synthesis examples.In addition,this review offers insights into future developments for advanced task-specific hollow structured porous materials prepared by the CNP strategy.

In order to improve the interface wettability as well as the interfacial bonding between graphene and copper matrix,in this work,graphene nanoplates modified with nickel nanoparticles(Ni-GNPs)were synthesized using a one-step method based on spray-drying and chemical vapor deposition.Thereafter,0.33 wt%Ni-GNPs were introduced into copper matrix composite by the molecular-level mixing method,leading to further enhancement of 90%in yield strength.This is attributed to the presence of Ni-GNPs,which provided high resistance to matrix against deformation.In addition,with the modification of nickel at the interface,the wettability and interfacial bonding between graphene nanoplates and copper matrix were improved,which enhanced the load transfer then.Furthermore,the microstructures and strengthening mechanisms were investigated and discus sed meanwhile.
