Preparation of Ni-geopolymer nanocomposite as an efficient catalyst for the reduction of nitro compounds

Geopolymer was presented as a new substrate for Ni nanoparticles with low cost and high stability features. Ni-geopolymer nanocomposite was used in the reduction of nitroaromatic compounds. The reactionwas performed in aqueous media and in the room temperature. Results showed that, the reaction time is very short and catalyst shows high activity under mild condition.
