NOVELTY - Preparation of single-atom noble metal/graphene catalyst, involves electrochemical intercalation and ultrasonic stripping of graphite, such that the noble metal salt is loaded on graphene, and reducing by microwave radiation. USE - Preparation of single-atom noble metal/graphene catalyst (claimed) for hydrodechlorination of p-chlorophenol to prepare methylcyclohexane. ADVANTAGE - The method provides catalyst comprising active component noble metal highly dispersed in atomic level and stably loaded in a high amount on graphene, and having excellent activity, selectivity and stability.
