▎ 摘　　要

MoO3-reduced graphene oxide nanocomposite is synthesized in a facile, time-saving and environmental friendly microwave assisted synthesis route. The as-prepared samples, MoO3 and MoO3-reduced graphene oxide are characterized by XRD, Raman, XPS, SEM, and TEM. The characteristic studies have confirmed the formation of MoO3 and its composite matrix with reduced graphene oxide. The electrochemical studies are carried out in three-electrode set up, and in two-electrode configuration to find the suitability of the as-prepared material for asymmetric supercapacitor applications. The galvanostatic charge/discharge profile of rGO//MoO3-rGO exhibits an excellent electrochemical activity with a specific capacitance of 133.68F g(-1) at 3A g(-1) with energy density and power density of 36.2 Wh Kg(-1) and 535.6W Kg(-1) respectively. The asymmetric supercapacitor device attains 85% of cyclic stability even after 4000 charge/discharge cycles.
