NOVELTY - A graphene oxide-cadmium sulfide complex (I) comprises reduced graphene oxide (GO) with nanogates on the surface of a single layer and between the bi-layers of the reduced graphene oxide. USE - Graphene oxide-cadmium sulfide complex used as catalyst for photocatalytic hydrogen generation (claimed). ADVANTAGE - The complex (I) acts as catalyst in hydrogen production exhibits around 34 times higher activity than its counterpart's materials. The photocatalytic hydrogen generation process exhibits 80-90 % enhancement in hydrogen generation. DETAILED DESCRIPTION - A graphene oxide-cadmium sulfide complex of formula (I) comprises reduced graphene oxide (GO) with nanogates on the surface of a single layer and between the bi-layers of the reduced graphene oxide. G=graphene layer;and r=reduction of edge side groups from graphene oxide layers. INDEPENDENT CLAIMS are included for the following: manufacture of graphene oxide-cadmium sulfide complex (I), which involves heating a solution mixture of graphite oxide (GO) of cadmium-acetate in N-methylpyrrolidone solution at 80-130° C for 1.5-2 hour to obtain a solution (A), heating a solution mixture of cadmium acetate dihydrate in N-methyl-2-pyrrolidone at 50-60° C for 5-10 minutes followed by adding polyethylene glycol of cadmium-acetate to obtain solution (B), adding the solution (B) into the solution (A), followed by stirring at 80-100° C for 1-2 hours to obtain solution (C), heating a solution mixture of sodium sulfide in N-methyl-2-pyrrolidone and water, preferably deionized water at temperature of 50-60° C for 1 to 2 hours to obtain solution (D), adding the solution (D) into solution (C) obtained at step (c), followed by stirring for 1-3 hours at 80-100° C to obtain solution (E) and stirring the solution (E) at 60-100° C for 20-30 hours; and photocatalytic hydrogen generation through water splitting, which involves dispersing the graphene oxide-cadmium sulfide complex (I) as catalyst and cocatalyst in sodium sulfide and sodium sulfate followed by ultrasonically processing for 10-15 minutes, and purging with nitrogen followed by irradiation with light.
