Synthesis of nano - nickel metal loaded on Faujasite-Zeolite for reduction of p-nitro phenol to p-amino phenol

Abstract

N ICKEL nanoparticles and Ni supported on faujasite-zeolite were prepared by using a solution of nickel nitrate of appropriate concentrations. The catalysts with 2.5, 5 and 10% nickel were reduced with hydrazine hydrate in the presence of alkali and used in reduction of p-nitrophenol to p-aminophenol. The prepared Ni catalysts were characterised by X-ray and SEM before and after conducting the reduction of p-nitrophenol. The results showed that catalysts contain nano nickel were durable in reduction of p-nitro phenol to p-amino phenol. The Ni supported on faujasite-zeolite was more active than the unsupported Ni catalyst.
