Gold nanoparticles (AuNP’s)are synthesized in sustainable green method using Carboxy Methyl Cellulose (CMC) and employed as catalyst in the reduction of p-nitro aniline with NaBH4 to p-phenylene diamine. It is observed that the speed of reaction was fast due to their size, as particle size decreases surface area increases. It is also observed that the rate of reaction is fast with comparison with the other catalyst. This is because the nanoparticles have more effective surface area and posses less steric hindrance with p-nitro aniline and NaBH4 when compared to nanoparticles due to their shape. The recyclability of nanoparticles shows it is potential recyclable catalyst for industrial applications.
