Polymerized Riboflavin and Anthraquinone Derivatives for Oxygen Reduction Reaction
Abstract
<jats:title>Abstract</jats:title><jats:p>Hydrogen peroxide (H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub>) is identified as a promising reagent for fuel cells, reducing the dependency on carbon‐based fuels. In this work, electrochemically synthesized polymers are employed to improve the efficiency of the oxygen (O<jats:sub>2</jats:sub>) reduction reaction, thus producing H<jats:sub>2</jats:sub>O<jats:sub>2</jats:sub> in an environmentally friendly way. Two aminoanthraquinones, as well as riboflavin (vitamin B2), are successfully immobilized via oxidative electropolymerization onto both glassy carbon and carbon paper. Of the investigated compounds, polyriboflavin shows a high Faradaic efficiency toward O<jats:sub>2</jats:sub> reduction, even at a very low potential of only −0.1 V versus SHE. This catalytic effect is present in neutral and alkaline conditions, using both glassy carbon and carbon paper, but highly pronounced in neutral, aqueous solutions.</jats:p>
