WebIn this work, we couple the sulfite oxidation reaction with the 2e- route oxygen reduction reaction to operate as a self-driven sulfite/air fuel cell for H2O2 electrosynthesis. An Au-Pd/C catalyst is synthesized as the H2O2 electrosynthesis catalyst, which exhibits good 2e- route oxygen reduction reaction activity and selectivity.
