NOVELTY - Nickel-based non-noble metal photocatalytic promoter comprises nickel atoms dispersed in nitrogen-doped graphene oxide. USE - Nickel-based non-noble metal photocatalytic promoter. ADVANTAGE - Mixing a small amount of nickel atoms improves the electron transport efficiency of graphene, and increases the catalytic activity sites. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of nickel-based non-noble metal photocatalytic promoter comprising preparing graphene oxide by Hummers method, dissolving graphene oxide in water, obtaining 0.4-1 mg/ml graphene oxide aqueous suspension, ultrasonically processing for 1-3 hours, adding nickel chloride hexahydrate (NiCl2.6H2O), where ratio of NiCl2.6H2O and graphene oxide aqueous suspension is 1 ml:40-80 ml, freeze-drying, obtaining brown powder, placing in tubular furnace at 300-500 degrees C for 0.5-2 hours under argon and ammonia gas atmosphere, and obtaining black powder i.e. nickel-based non-noble metal photocatalytic promoter.
