Catalyst design, measurement guidelines, and device integration for H2O2 electrosynthesis from oxygen reduction

The electrosynthesis of H 2 O via a two-electron pathway oxygen reduction reaction (2e ? ORR) has emerged as promising way carbon-free and on-site production . Active selective electrocatalysts for the 2e ORR are essential achieving high -to-H conversion efficiency. In this review, we present recent progress in development including Pt-group-metal (PGM) non-PGM atomically dispersed catalysts metal-free heteroatom-doped carbons. impact active sites interface structures on electrocatalytic process is summarized. Benchmarking activities terms mass activity site-normalized presented to understand current status advancement provide an insight into possible future research directions. addition, some guidelines pitfalls typical laboratory measurements assessing performance proposed. Finally, advances high-current-density reactors devices that exploit electrosynthesized introduced. Lim et al. review catalyst design from ORR). Also discussed measurement ORR, integrated large-scale electrosynthesis, utilize
