Synthesis of ultra-small platinum, palladium and gold nanoparticles by Shewanella loihica PV-4 electrochemically active biofilms and their enhanced catalytic activities

الملخص EN

Ultra-small nanoparticles (USNPs) of noble metals have a great potential in a variety of applications due to their high surface areas and high reactivity.

This work employed electrochemically active biofilms (EABs) composed of a single bacterium strain of Shewanella loihica PV-4 and successfully synthesized USNPs of noble metal Au, Pd, and Pt.

The synthesized USNPs had a size range between 2 and 7 nm and exhibited excellent catalytic performance in dye decomposition.

The results of this work shine light on the use of EABs in nanoparticle synthesis.
