Summary: Lignin-derived carbon electrode materials with a high carbon content and a rich benzene ring structure were studied for supercapacitors, and it was found that the nanoporous structure significantly affects the capacitive performance. Three nitrogen-doped nanoporous carbons were prepared using alkali lignin as a carbon source, and the effect of different nanopore distributions on the electrochemical performance was examined. The carbon activated by ZnC2O4 showed a hierarchical porous structure composed of nanosheets, enabling it to store charge and transfer ions simultaneously. It achieved a maximum specific capacitance of 254F/g at 0.5 A/g, surpassing the microporous-dominated carbon activated by K2CO3 and mesoporous-dominated carbon obtained by the SiO2 template method. This study provides theoretical guidance for the preparation of excellent lignin-derived carbon electrode materials.

Summary: The effect of structural properties of fluorinated graphene (FG) on the supercapacitive properties in KI additive electrolyte was investigated. The adjustment of porous structure and surface F element content of FG through chemical reduction and heating treatment led to a dramatic increase in specific capacitance in KI additive electrolyte compared to pure H2SO4 electrolyte. The relationship between F content and areal capacitance revealed that a small amount of F content, particularly semi-ionic C-F species, can effectively promote the areal capacitance. The assembled symmetric supercapacitor with moderate F content and high specific surface area exhibited an energy density of 8.89 Wh kg-1 and long cyclic stability.

Summary: Zinc phytate was used as a sacrificial template to synthesize porous carbon for supercapacitors. The resulting carbon material had a hierarchically porous structure with a specific surface area of 1125 m(2) g(-1). Adjusting the pore structure was achieved by introducing KOH during the preparation of the phytate salt, leading to an increase in micropore content. The introduction of in-situ K activation instead of KOH activation resulted in the formation of dual-metal phytates and contributed to the micropores in the prepared carbon material. With increased microporosity, the specific capacitance of the carbon material improved.

Summary: We synthesized a carbon nanotubes-en-capsulated Ni nanoparticles catalyst through a facile chemical vapor deposition approach for electrochemical CO2 reduction (ECR). The Ni@N-C catalyst exhibited the highest CO Faraday efficiency (FECO%) of 90% at -0.77 V vs. RHE in the H-type cell. Moreover, it showed a high FECO% of over 93% within the range of -0.37 to -0.77 V vs. RHE in the flow cell. The excellent catalytic performance of Ni@N-C suggests that N-doped carbon nanotubes coated on Ni nanoparticles play a vital role in promoting ECR activity. This work provides insights into the development of a simple and efficient electrocatalyst for ECR.

Summary: In this study, a MOF-derived Cu/SiO2 catalyst was developed for the furfural (FF) hydrogenation reaction, which showed superior catalytic performance compared to Cu/SiO2 catalysts prepared by traditional methods. The Cu/SiO2-MOF catalyst not only anchored copper species on the silica surface via Cu-O-Si bonds, but also exposed more active sites, resulting in a higher Cu+/(Cu+ + Cu-0) ratio and richer oxygen defects. The solvent effect on product distribution was found to play an important role in adjusting selectivity. This research provides insights into the catalytic mechanism of Cu/SiO2-MOF and has implications for the design and synthesis of efficient catalysts in other heterogeneous catalysis fields.
