Thermal Decomposition Synthesis of MoO3 for Application in Electrochemical Supercapacitors

MoO₃ was synthesized by thermal decomposition of ammonium molybdate. The structure and surface morphology of the as-prepared MoO₃ was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The supercapacitive behaviour of MoO₃ in 1 mol L^-1 KCl electrolyte was studied by cyclic voltammetry (CV), galvanostatic charge-discharge cycling (CD). The affect of thermal decomposition temperature on the capacitive behaviour of MoO₃ was also discussed here. The results indicate that MoO₃ show good capacitive behaviour with a specific capacitance of 148.9 F g^-1 at 0.7 A g^-1. Thermal decomposition temperature has an important influence on the capacitive behaviour and crystallization of MoO₃.
