Summary: A simple and robust approach was employed to synthesize one-dimensional hollow tubular carbon-based materials with highly efficient oxygen reduction reaction performance. By simultaneously crafting single-atomic Fe sites and graphitic layer-wrapped Fe3C nanoparticles, the Fe-N-doped hollow mesoporous carbon tubes were successfully prepared and used as the ORR electrocatalyst. The impressive ORR performances of the Fe-N-HMCTs are attributed to the favorable configuration of active sites in conjunction with the advantageous 1D hollow tubular architecture.

Summary: Introduction of the photothermal effect improves the performance of transition-metal oxide photoanodes in photoelectrochemical water-splitting. However, the specific role of photothermal effect on the performance is not well understood. This study explores the use of ZnFe2O4/Fe2O3 photoanode and identifies that the improved performance is due to the enhanced mobility of electron small polarons bound to oxygen vacancies, activated by the photothermal effect. The synergy between oxygen vacancies and the photothermal effect significantly improves the electron conductivity and photoelectrochemical performance.

Summary: A one-step pyrolysis-free approach was developed to synthesize core-shell coaxially heterostructured CNTs/Co-N,O-CPs for efficient oxygen reduction reaction (ORR). The CNTs/Co-N,O-CPs exhibited a 1D heterostructure with abundant hierarchical porosity, allowing for efficient exposure of active sites and fast electron and mass transport. Theoretical calculations revealed the strong orbital interaction between Co and coordinated O atoms, which optimized the adsorption strengths of ORR intermediates and enhanced the intrinsic activity of CNTs/Co-N,O-CPs. The CNTs/Co-N,O-CPs demonstrated superior performance in ORR and zinc-air batteries, surpassing previously reported carbon-based SMACs and even outperforming the state-of-the-art Pt/C catalyst.

Summary: Recent advancements in the development of cost-effective and high-efficiency transition metal-based electrocatalysts have led to a better understanding of the dynamic reconstruction of surface structures during electrocatalytic water oxidation, especially the anodic oxygen evolution reaction (OER). Through operando and in situ techniques, it has been found that electrocatalysts undergo surface reconstruction to form actual active species during OER in alkaline solution. By exploring issues such as initiators for surface reconstruction and establishing relationships between structure, composition, and electrocatalytic activity, progress has been made in the rational manipulation of in situ catalyst surface reconstruction for the development of high-efficiency electrocatalysts.
