Abstract |
Graphene (G), a two-dimensional carbon layer, is regarded as twenty-first century wonder material
and due to its remarkable physio-chemical properties it has been explored for application in
various science and technology areas. In environmental remediation field, the quest for ecofriendly
and green processes has put a growing emphasis on solar-driven photocatalysis. The
conventional semiconductor photocatalysts suffer with the shortcoming of electron–hole pair
recombination, aggregation and wide band gap, which inhibit their commercialization.
Coupling of graphene derivatives, such as graphene oxide (GO) and reduced graphene oxide
(RGO), with semiconductors (TiO2, ZnO) offers a considerable potential to enhance the
photocatalytic efficiency by providing higher surface area, stability, and fast electron conduction
ability. Numerous papers have been published in recent years which couples Graphene, GO and
RGO with different semiconductors for photocatalytic degradation of various organi
