A review on graphene based transition metal oxide composites and its application towards supercapacitor electrodes

摘要

Two-dimensional (2D) graphene and its outstanding properties such as, enormous conductivities, mechanical strength,optical and electrical properties brought it one of the most studied materials for the production of energy using renewableresources. The composites of graphene with the same morphological materials such as layered transition metaloxides will be the most aspiring combination to boost their conducting, optoelectronic and mechanical properties. Furthermore,the transition metal chalcogenides materials attracted significant attention due to their atomically thin layersand enormous optical, conducting and electrical properties. The layered materials offer mostly atomically thin 2D planeto the charge carrier with superior conducting properties. The thickness at atomic level, band gap, spin orbit couplingelectronic and optoelectronics properties of transition metal dichalcogenides makes them one of the promising entitiesin energy harvesting technologies. The review suggests some strategies to improve the transition metals-compositesstability conducting properties to be tailored in various applications.
