Nano immobilization of enzyme to improvement of biofuel cell electrode's function

Abstract

This study centers on development of the enzyme presentation as a cathode catalyst. Laccase enzyme is immobilized at nano meter scale in quaternary ammonium bromide salt treated Nafion polymers and assorted with high surface area carbon powders that are then deposited onto a solid support to create the cathode electrode. Optimization of the synthesis circumstances resulted in notably enhanced performance toward oxygen reduction reaction. © 2010 Asian Network for Scientific Information.
