Using alkaline pH adjustment, the reaction between graphene oxide and L-ascorbic acid led to formation of a carbocatalyst film with numerous edges protruding out basal planes, which had markedly enhanced carbocatalytic activity for conversion 4-nitrophenol 4-aminophenol, as compared that counterpart without involving mediation.
