Bioinspired Reduced Graphene Oxide Based Nanohybrids for Photocatalysis and Antibacterial Applications

Ultra-thin graphene has been receiving a spacious significance in the diverse sections of material science, owing to its exceptional physicochemical and thermo-mechanical characteristics. Currently, the fabrication of high-grade graphene in an economical target and green procedures area is a massive concern. Among the diverse techniques, chemical-mediated fabrication is believed to be the finest process, since it is simple, scalable, and low-priced, however, therein involved noxious or hazardous chemical reducers to produce the functional graphene-based nanocomposites (NCs). Hence, globally scientists are continuously endeavoring to adopt the bioinspired procedures to manufacture the functional reduced graphene oxide (rGO) and reduced graphene oxide-metal/metal oxide (rGO-M/MO) NCs. Hence, keeping this issue in our mind, the present review article summarizes and integrates the current state of knowledge on diverse strategies for bioinspired fabrication of rGO and rGO-M/MO NCs and their photocatalytic, antibacterial, and cytotoxicity assessments.
