▎ 摘 要
Hybrid CoMoO4 nanorods with carbon (C) and graphene oxide (rGO) are successfully synthesized via one-step hydrothermal process. Hybrid alpha-CoMoO4 nanorods have shown excellent electrochemical performances compared to pristine CoMoO4 in alkaline electrolyte. Specifically, CoMoO4/C nanorod exhibits a maximum specific capacitance of 451.6 F g(-1) at the current density of 1 A g(-1), whereas CoMoO4/rGO shows high specific capacitance of 336.1 F g(-1) at the same current density. Both the hybrid nanorods show good rate capability even at high current density of 20 A g(-1) and long-term cyclic stability. The observed electrochemical features of the hybrid CoMoO4 nanostructure could be attributed to the presence of highly conductive carbonaceous material on unique one-dimensional nanorod microstructure which enhances the electrical conductivity of the nanorods thereby allowing faster electrolyte ion diffusion during the redox process.
