Abstract

Glucose biofuel cells are one of the promising power supplies with a competent long-term stability and power density. In this respect, catalysts of palladium (Pd) and platinum (Pt) metal nanoparticles film coated electrode were fabricated for biofuel cell. The Pt and Pd particles were electrochemically deposited onto glassy carbon (GC) electrode modified with poly(1,8-diaminonaphthalene), (p-1,8-DAN), via single or layer-by-layer electrodeposition. In results, Pt/p-1,8-DAN/GC, Pd/p-1,8-DAN/GC, Pt-Pd/p-1,8- DAN/GC and Pd-Pt/p-1,8-DAN/GC shell-core catalysts were fabricated and characterized by several ana- lytical techniques such as AFM, EDX,SEM, TEM, and XPS, in addition to electrochemical methods. Their catalytic electrooxidation behaviors of glucose were investigated in alkaline medium. The as-prepared nano-catalysts showed improved electrocatalytic performances and better stability for glucose oxidation reaction (GOR) due to the presence of metal nanoparticles. The Pd as core and Pt as shell in Pt-Pd/p-1,8- DAN/GC catalyst exhibited higher electrochemically accessible surface area (157.58 m 2 /g) and a favored electrooxidation efficiency. Moreover, the bimetallic Pt-Pd shell-core electrode showed higher resistance to poisoning (tolerance 1.24) and a decrease in the onset potential to -0.28 V. These multipurpose electro- catalysts are a potential candidate for developing a novel glucose biofuel cell.
