Research Abstract

A novel catalyst for nitrate ion reduction was developed by synthesizing CuPd particles in the protein cage of apoferritin. The apoferritin containing CuPd particles (CuPd-apoFr) was analyzed using TEM, XRD, and EXAFS and it was revealed that CuPd alloy nanoparticles were formed inside of the apoferritin. CuPd-apoFr showed catalytic activity for nitrate ion reduction.
