A robust strategy to boost the proton transfer of heterogeneous catalysts for efficient and sustainable water oxidation towards practical applications

Abstract

As the much larger mass of proton than electron, the oxygen evolution reaction (OER) on heterogeneous electrocatalysts usually undergoes slow proton/fast electron transfer, which greatly limits the OER performance. Boosting...

Oxygen Vacancy-Originated Inorganic Proton Relay for the Oxygen Evolution Reaction: Fast Proton Hopping via La-Doped Praseodymium Carbonate Hydroxide

“…NF/PrCH exhibited the least stable response as the current gradually declined from the beginning of the electrolysis. The observed decay may be related to the sluggish PT and local corrosion of the catalyst because of the spatiotemporal accumulation of the protons, and thus, their corrosion in harsh conditions. , In sharp contrast, NF/LaPrCH demonstrated exceptional stability, maintaining a consistent current density for the entire 24 h duration without any noticeable decay. The Sr-LaPrCH exhibits a comparatively lower level of stability when compared to LaPrCH.…”
