Abstract
Nickel 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 contains 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.
