Bifunctional P-Containing RuO₂ Catalysts Prepared from Surplus Ru Co-Ordination Complexes and Applied to Zn/Air Batteries.

ABSTRACT: An innovative synthetic route that involves the thermal treatment of selected Ru co-ordination complexes was used to prepare RuO₂-based materials with catalytic activity for oxygen reduction (ORR) and oxygen evolution (OER) reactions. Extensive characterization confirmed the presence of Ru metal and RuP₃O₉ in the materials, with an improved electrocatalytic performance obtained from calcinated [(RuCl₂(PPh₃)₃]. A mechanistic approach for the obtention of such singular blends and for the synergetic contribution of these three species to electrocatalysis is suggested. Catalysts added to carbon-based electrodes were also tested in all-solid and flooded alkaline Zn/air batteries. The former displayed a specific discharge capacity
