“…Despite their good conductivity, precious metals are too expensive and scarce to be used widely. 31 In addition, carbon-based materials are broadly used in environmental applications, such as g-C 3 N 4 , 32 MWCNTs, 33 CNTs, 34 CNF 35 and rGO. Specifically, rGO is a significant promising material due to its potential application in photodegradation, H 2 production, energy conversion and CO 2 reduction.…”
