Abstract

New catalyst for promoting oxygen reduction reaction (ORR) and enzymatic biofuel cell (EBC) performance is suggested. The catalyst consist of laccase (LAC) and gold nanoparticle (GNP)-naphthalenethiol (NPT), which are linked to polyethyleneimine (PEI) and carbon nanotube (CNT) (CNT/PEI/[GNP-NPT]/LAC). Its onset potential and ORR rate are improved due to adoptions of PEI and GNP-NPT. Namely, CNT/PEI induces more immobilization of LACs and GNP-NPT acts as electron relay between CNP and NPT by thiol-gold bond and between CNT/PEI and LACs by electron collection effect. Even in EBC measurement, maximum power density of EBC using CNT/PEI/[GNP-NPT]/LAC is highest as 13 μW cm⁻².
