The photocatalyst was used for the reduction of nitroaromatic compounds to their corresponding aromatic amines with hydrazine monohydrate. The catalyst showed the best activity in the reduction of 1,4-dinitrobenzen (%97 conversion in 40 min). The recyclability and reusability of the catalyst was evaluated for four times which showed no significant variation in the conversion of nitrobenzene photoreduction reaction.
