The redox reaction of vanadium ions (V2+↔3+↔4+↔5+) on well-developed nitrogen-doped ordered mesoporous carbon (NOMC) was extensively investigated in different electrolyte solutions by electrochemical methods. It is found that both the electronic structure modulated by nitrogen doping and the enriched electrochemically active functional groups on NOMC favor the three electrochemical transitions between...
A novel hierarchical starfish-like vanadium oxide is synthesized by a simple and direct hydrothermal method using a functional V2O5 sol as a vanadium source. The formation mechanism of hierarchical starfish-like structure is discussed. Results demonstrate that the functional V2O5 sol plays a crucial role in the formation of a hierarchical starfish-like structure. Starfish-like vanadium oxide is composed...
