Опубликована: Июнь 29, 2020

Abstract Reducing green hydrogen production costs is essential for developing a economy. Developing cost‐effective electrocatalysts water electrolysis thus of great research interest. Among various material candidates, transition metal phosphides (TMP) have emerged as robust bifunctional both the evolution reaction (HER) and oxygen (OER) due to their phases tunable electronic structure. Recently, heterostructured catalysts exhibited significantly enhanced activities toward HER/OER. The enhancement can be attributed increased amount accessible active sites, accelerated mass/charge transfer, optimized adsorption intermediates, which arise from synergistic effects heterostructure. Herein, comprehensive overview recent progress TMP‐based heterostructure introduced provide an insight into preparation corresponding mechanisms. It starts with summarizing general fundamental aspects HER/OER effect heterostructures catalytic activity. Next, innovational strategies design construct overall splitting activity, well related mechanisms, are discussed in detail. Finally, summary perspective further opportunities challenges highlighted development points practical application mechanistic studies.

Most reported catalysts for water oxidation undergo in situ electrochemical tuning to form the active species their oxygen evolution reaction (OER). In general, transformations of non-oxide are faster than those corresponding oxides, and they typically display improved OER activity. Although many approaches surfaces as well investigations into roles mechanism adsorption intermediates have been reported, we still a poor understanding dominant sites formed during OER.
