摘要：Highly ordered metal oxide nanorods (MnO2, SnO2, NiO) inside mesoporous silica supported carbon nanomembranes have been applied for electroactive materials to fabricate symmetrical supercapacitors. Maximum specific capacitance of the obtained cells reaches up to 964 F g(-1) in aqueous electrolyte with energy density of 33.5 Wh kg(-1) for a 1 V voltage window, which are among the highest values in two electrodes supercapacitor cells employing similar metal oxide/carbon materials. This high performance is attributed from the synergic effect of the conductive carbon nanomembrane and well-ordered pseudocapacitive metal oxide nanorods.
