A number of methods have been developed for the synthesis of the Au NPs on the graphene oxide (GO)/rGO nanosheets such as chemical reduction, electrochemical deposition, photo-assisted reduction, sonochemical methods, and microwave irradiation [19-24]. 

In the field of catalysis, Au NPs appear to be particularly important as an efficient catalyst in organic reactions it can offer the most favourable combination of activity and selectivity in various catalytic reactions such as electrocatalysis, redox catalysis, carbon-carbon bond formation, and photocatalytic reactions. Moreover, recent literature reported that the Au NPs-graphene composites exhibit unprecedented catalytic activity for CO oxidation, reduction of nitro-aniline and Suzuki-Miyaura coupling reaction of chlorobenzene with arylboronic acid.
