Development of Ruthenium-Based Catalysts for Oxygen Reduction Reaction

Abstract

A process was developed to synthesize ruthenium-based chelate RuNx electrocatalysts for the oxygen reduction reaction, using RuCl3 and propylene diammine as the Ru and N precursors, respectively. High-temperature pyrolysis has a critical role in the formation of the catalytic Ru–N sites for oxygen reduction. The RuNx catalyst modified in the presence of… (More)
