Optimizing electrochemical performance: Investigating the influence of oxidation of graphene oxide in rGO@MnMoO4
Source abstract
Abstract
This investigation delves into the intricacies of controlled oxidation of graphene oxide (GO) and its influence on the electrochemical performance of reduced graphene oxide (rGO) and Manganese Molybdate based composites. Further, through a meticulous manipulation of GO composition, we achieve the hydrothermal synthesis of rGO@MnMoO 4 composites, wherein the most optimized configuration exhibited a remarkable specific capacity of 1356 C/g and 1299 C/g at 10 mV/s and 2 A/g, respectively. This achievement is ascribed to the intricately designed microporous microrod morphology of MnMoO 4 , synergistically coupled with the electrical conductivity enhancement facilitated by rGO, attributed to its abundant conjugated carbon bonds. The results further culminate in the development of an asymmetric supercapacitor (ASC) denoted as rGO@MnMoO 4 // graphite-activated carbon (G-AC), demonstrated altitudinous energy density of 63.5 Wh/kg at power density of 850 W/kg. Notably, this formidable device demonstrated an excellent stability by retaining 97% of specific capacity after 9460 cycles, evincing minimal structural and morphological degradation.
