In the present article, an easy synthetic strategy of a novel composite photo-catalyst comprising of
amino-functionalized reduced graphene oxide and Cu2O has been proposed. Role of this composite
catalyst in photo reduction of CO2 has been analyzed and it is shown that both amino groups and
reduced grapheme oxide, participate in enhancing quantum yield of the photo reduction process.
