Fe/N-based biomass porous carbon composite(Fe/N-p carbon) was prepared by a facile high-temperature carbonization method from biomass,and the effect of Fe/N-p carbon on the thermal decomposition of energetic molecular perovskite-based material DAP-4 was studied.Biomass porous carbonaceous materials was considered as the micro/nano support layers for in situ deposition of Fe/N precursors.Fe/Np carbon was prepared simply by the high-temperature carbonization method.It was found that it showed the inherent catalysis properties for thermal decomposition of DAP-4.The heat release of DAP-4/Fe/N-p carbon by DSC curves tested had increased slightly,compared from DAP-4/Fe/N-p carbon-0.The decomposition temperature peak of DAP-4 at the presence of Fe/N-p carbon had reduced by 79°C from384.4°C(pure DAP-4) to 305.4°C(DAP-4/Fe/N-p carbon-3).The apparent activation energy of DAP-4thermal decomposition also had decreased by 29.1 J/mol.The possible catalytic decomposition mechanism of DAP-4 with Fe/N-p carbon was proposed.

Although biomass-derived carbon(biochar)has been widely used in the energy field,the relation between the carbonization condition and the physical/chemical property of the product remains elusive.Here,we revealed the carbonization condition's effect on the morphology,surface property,and electrochemical performance of the obtained carbon.An open slit pore structure with shower-puff-like nanoparticles can be obtained by finely tuning the carbonization temperature,and its unique pore structure and surface properties enable the Li–O_(2) battery with cycling longevity(221 cycles with 99.8%Coulombic efficiency at 0.2 mA cm^(−2) and controlled discharge–charge depths of 500 mAh g^(−1))and high capacity(16,334 mAh g^(−1) at 0.02 mA cm^(−2)).This work provides a greater understanding of the mechanism of the biochar carbonization procedure under various pyrolysis conditions,paving the way for future study of energy storage devices.

Catalytic cracking oil slurry is a by-product of catalytic cracking projects,and the efficient conversion and sustainable utilization of this material are issues of continuous concern in the petroleum refining industry.In this study,oxygen-enriched activated carbon is prepared using a one-step KOH activation method with catalytic cracking oil slurry as the raw material.The as-prepared oil slurry-based activated carbon exhibits a high specific surface area of 2102 m^(2)/g,welldefined micropores with an average diameter of 2 nm,and a rich oxygen doping content of 32.97%.The electrochemical performance of the nitrogen-doped porous carbon is tested in a three-electrode system using a 6 mol/L KOH solution as the electrolyte.It achieves a specific capacitance of up to 230 F/g at a current density of 1 A/g.Moreover,the capacitance retention rate exceeds 89%after 10000 charge and discharge cycles,demonstrating excellent cycle stability.This method not only improves the utilization efficiency of industrial fuel waste but also reduces the production cost of supercapacitor electrode materials,thereby providing a simple and effective strategy for the resource utilization of catalytic cracking oil slurries.

In order to deal with the increasingly serious environmental problems,it is important and necessary to lower the concentration of greenhouse gases,especially the CO_(2)gas.CO_(2)capture and storage are the relative suitable options for the reduction of these harmful gas concentration.Through the variation of mass ratio of KOH to bio-char,the as prepared active carbon PC-4 exhibits a higher specific surface area of 2491.57 cm^(3)·g^(−1),with the ultra-micropores of 0.5 and 1.2 nm.At 298 K/1 bar,the CO_(2)adsorption capacity of PC-4 also represents the highest value of 5.81 mmol/g.This work demonstrates that the both the pore size and the specific surface area are equally important to enhance the CO_(2)adsorption.This work provides a sustainable method to develop high efficiency waste-based adsorbents to deal with environmental issues of CO_(2)gas.

For the continuous utilization of nuclear energy and efficient control of radioactive pollution, low-cost materials with high efficient U(VI) removal are of great importance. In this study, low temperature plasma method was applied for the successful modification of Ophosphorylethanolamine(O-PEA) on the porous carbon materials. The produced materials(Cafe/O-PEA) could adsorb U(VI) efficiently with the maximum sorption capacity of 648.54mg/g at 1 hr, T=298 K, and p H=6.0, much higher than those of most carbon-based composites. U(VI) sorption was mainly controlled by strong surface complexation. From FTIR,SEM-EDS and XPS analyses, the sorption of U(VI) was related to the complexation with-NH2, phosphate and-OH groups on Cafe/O-PEA. The low temperature plasma method was an efficient, environmentally friendly and low-cost method for surface modification of materials for the effective enrichment of U(VI) from aqueous solutions.

Rutin,a flavonoid found in fruits and vegetables,is a potential anticancer compound with strong anticancer activity.Therefore,electrochemical sensor was developed for the detection of rutin.In this study,CoWO_(4) nanosheets were synthesized via a hydrothermal method,and porous carbon(PC)was prepared via high-temperature pyrolysis.Successful preparation of the materials was confirmed,and characterization was performed by transmission electron microscopy,scanning electron microscopy,and X-ray photoelectron spectroscopy.A mixture of PC and CoWO_(4) nanosheets was used as an electrode modifier to fabricate the electrochemical sensor for the electrochemical determination of rutin.The 3D CoWO_(4) nanosheets exhibited high electrocatalytic activity and good stability.PC has a high surface-to-volume ratio and superior conductivity.Moreover,the hydrophobicity of PC allows large amounts of rutin to be adsorbed,thereby increasing the concentration of rutin at the electrode surface.Owing to the synergistic effect of the 3D CoWO_(4) nanosheets and PC,the developed electrochemical sensor was employed to quantitively determine rutin with high stability and sensitivity.The sensor showed a good linear range(5-5000 ng/mL)with a detection limit of 0.45 ng/mL.The developed sensor was successfully applied to the determination of rutin in crushed tablets and human serum samples.

Potassium-ion hybrid capacitors(PIHCs)as a burgeoning research hotspot are an ideal replacement for lithium-ion hybrid capacitors(LIHCs).Here,we report nitrogen-doped porous carbon nanosheets(NPCNs)with enlarged interlayer spacing,abundant defects,and favorable mesoporous structures.The structural changes of NPCNs in potassiation and depotassiation processes are analyzed by using Raman spectroscopy and transmission electron microscopy.Due to the unique structure of NPCNs,the PIHC device assembled using NPCNs as both the anode and cathode material(double-functional self-matching material)exhibits a superior energy density of 128 Wh kg^(-1)with a capacity retention of 90.8%after 9000 cycles.This research can promote the development of double-functional self-matching materials for hybrid energy storage devices with ultra-high performance.

The practical applications of lithium-sulfur(Li-S)batteries are limited by the low conductivity of sulfur and the shuttle effect of soluble polysulfides during the charge-discharge process.At the same time,biomass-based carbon materials have been acknowledged as the cost-effective and direct settlement to mitigate or overcome these problems due to their renewability,facile processing,and pollution-free characteristics.Therefore,in this work,we report the natural nori-based CoO nanoparticles decorated hierarchical porous carbon(HPC)for high-capacity Li-S battery cathodes.The HPC with an extremely high surface area of 2089 m^(2)g^(−1)provides a good substrate for the accommodation of CoO nanoparticles,which can effectively seize the lithium polysulfides and facilitate their redox conversion.As a result,the CoO-HPC/S cathode exhibits a high discharge capacity of 1557.1 mA h g^(−1),as well as excellent rate performance and cycling stability.Due to the naturally abundant nori-based cathode materials,the resultant Li-S battery is supposed to be an attractive and sustainable energy storage device.

Lignocellulosic biomass such as plants and agricultural waste are ideal to tackle the current energy crisis and energy-related environmental issues.carbon-rich lignin is abundant in lignocellulosic biomass,whose high-value transformation and utilization has been the most urgent problem to be solved.Herein,we propose a method for the preparation of porous carbon from lignin employing an H_(3)PO_(4)-assisted hydrothermal method.We characterize the as-prepared lignin-derived porous carbon and investigate its potential for energy storage.After assisted hydrothermal treatment followed by carbonization at 800℃,the lignin-derived porous carbon displays a high specific capacitance(223.6 F·g^(–1) at 0.1 A·g^(–1))and excellent cycling ability with good capacitance retention.In this present study,the resultant lignin-derived porous carbon was used as the electrode of a supercapacitor,illustrating yet another potential high-value use for lignin,namely as a candidate for the sustainable fabrication of main supercapacitor components.
