Novel phosphorus-doped lead oxide electrode for oxygen evolution reaction

Abstract

A facile and cost-effective electrochemical approach was proposed for the first time to prepare a phosphorus-doped lead dioxide (P-PbO₂) electrode on a lead substrate. This was achieved by introducing a pyrophosphate solution containing Cu²⁺, F⁻ and peptone as essential additives. Such a novel P-PbO₂ electrode exhibits a significantly improved electrocatalytic activity for the oxygen evolution reaction as compared to a traditional Pb/PbO₂ electrode.
