Improved electrochemical performance of rGO-wrapped MoO3 nanocomposite for supercapacitors
A low-cost hydrothermal method has been employed to synthesize phase pure α-MoO 3 and MoO 3 /rGO nanocomposite electrodes with novel structures for high-performance supercapacitors. Both nanocomposites exhibited orthorhombic layered structure. Pure MoO 3 exhibited nanorod-like morphology, whereas Mo...
