This present work demonstrates the integration of oxygen atoms into the graphene matrix to develop graphene oxide (GO) with tailored oxidation degrees which render them as photoactive materials for hydrogen (H2) evolution. GO photocatalysts derived from the modified Hummer’s method can endow tunable optical and electronic properties by varying the oxidation level into three increasing degrees GO-0...
A novel photocatalyst with core@shell structure was prepared by alternately assembling titania nanosheets (TNS) and reduced graphene oxide (r-GO) on coal fly ash (CFA) microspheres via the layer-by-layer (LBL) assembly approach. The as-prepared samples CFA@(r-GO/TNS)n were characterized by SEM, HRTEM, XRD, FTIR, Raman, XPS, UV–vis, PL and their photocatalytic activities were evaluated by the photodegradation...
