Cerium-based metal sulfide derived nanocomposite-embedded rGO as an efficient catalyst for photocatalytic application.

Reduced graphene oxide (rGO) with metal sulfides is an efficient photocatalyst for treating textile effluent. Herein, a hydrothermal technique was used to synthesize transition metal sulfide with rGO nanocomposite. Under 120 min of sunlight exposure, the cerium-nickel sulfide/rGO nanocomposite (CeS-NiS/rGO) photodegraded the methyl orange (MO) dye with an efficiency of 89.
