Extraordinary pseudocapacitive energy storage triggered by phase transformation in hierarchical vanadium oxides [PDF]

Nature Communications, 2018
Pseudocapacitive materials could enable high-performance electrochemical supercapacitors, but their practical capacitance and power density remain low. Here the authors show that in situ phase transformation triggers extraordinary pseudocapacitive energy

Selective oxidation of isobutane on V-Mo-O mixed oxide catalysts [PDF]

Journal of the Serbian Chemical Society, 2008
Four V-Mo-O mixed metal oxides were prepared, characterized and tested for the selective oxidation of isobutane in the temperature range 350-550°C, at atmospheric pressure. Isobutane was mainly oxidized to isobutene and carbon oxides.

Conductive coating, cation‐intercalation, and oxygen vacancies co‐modified vanadium oxides as high‐rate and stable cathodes for aqueous zinc‐ion batteries

EcoMat, 2023
Layered vanadium oxides are promising cathode materials for zinc‐ion batteries (ZIBs) owing to their high capacity, but the sluggish electron/ion migration kinetics and structural collapse/dissolution severely limit their Zn2+‐storage performance. Herein,
