Protein mediated synthesis of gold nanobiocatalyst by microwave: A high efficient catalytic activity for the selective oxidation of benzyl alcohol

• An efficient, one pot protein mediated synthesis of gold nanobiocatalyst by microwave.
• AuNBC exhibited excellent stability over a wide range of pH and temperature.
• One-pot oxidation of benzyl alcohol using AuNBC under microwave heating.
• Environmentally benign with non-toxic reagents and high recyclability.
• Benchmarked catalytic activity of the synthesized AuNBC with other nanomaterials.

A simple, proficient, one-pot green chemical method for the biosynthesis of gold nanoparticles (AuNPs) with protein egg albumin by microwaves, which produce novel gold nanobiocatalyst (AuNBC) and it was characterized by FT-IR, UV–vis, TEM and DLS, which exhibited excellent stability over a wide range of pH and temperature. The catalytic activity of the as-synthesized AuNBC was quantified by synthesizing sodium benzoate from the one-pot oxidation of benzyl alcohol using gold nanobiocatalyst under microwave heating, which was stronger than AuNPs prepared by conventional chemical methods. The protocol is environmentally benign with non-toxic reagents, high recyclability and high efficiency.
