Abstract
En 中文
• Cr2(MoO4)3 was synthesized through hydrothermal route followed by thermal crystallization. • Underexplored Cr–Mo oxide was investigated as a supercapacitor electrode for the first time. • Cr2(MoO4)3 exhibited significantly enhanced performance compared with Cr2O3 and MoO3. • DFT calculations revealed preferential K adsorption at oxygen-rich surface sites, providing insight into the charge-storage mechanism. • Symmetric supercapacitors delivered high Csp (247.62 F/g at 0.714 A/g) and excellent long-term cycling stability.
