Description
Summary:One-pot synthesis of Ni nanoparticles was carried by solution reduction process successfully in aqueous media by using hydrazine hydrate as a reducing agent. Greener stabilizing agent starch is used as a stabilizer, which also acts as a particle protector toward oxidation. The morphologies of the synthesized Ni nanoparticles were characterized by TEM and XRD. The prepared Ni nanoparticles were used as a catalyst in the reduction of p-nitrophenol to p-aminophenol under hydrothermal condition in the presence of sodium borohydrate as a source of hydrogen. The conversion was excellent (97%), as confirmed by LCMS. This also confirmed by the UV-visible spectrum study of the reaction mixture. The Ni nanoparticles were recycled at least five times without much loss in the catalytic activity.
