Title: Bioelectrocatalytic Carbon Ceramic Gas Electrode for Reduction of Dioxygen and Its Application in a Zinc-Dioxygen Cell
Abstract: An enzyme-modified carbon ceramic electrode was constructed and studied is capable to reduce dioxygen supplied from the gas phase. The of the electrode material and its hydrophobic silicate was studied by scanning electrochemical microscopy. The coefficient of dioxygen in methyltrimethoxysilane-based was estimated to be 6.44 x 10(-5) cm(2) s(-1). After of the electrode with bilirubin oxidase and immersion in aqueous electrolyte, the dioxygen bioelectrocatalytic is observed with onset potential at 0.45 V. The constructed electrode was successfully applied as cathode in a zinc-dioxygen cell.
