Exploring durable electrocatalysts with high activity for oxygen evolution reaction (OER) in acidic media is of paramount importance H2 production via polymer electrolyte membrane electrolyzers, yet it remains urgently challenging. Herein, we report a synergistic strategy Rh doping and surface vacancies to precisely regulate unconventional OER path the Ru-O-Rh active sites Rh-RuO2, simultaneously boosting intrinsic stability.

The /G displays robust acid oxygen evolution reaction performance mass of 671 A...
Significant progress has been demonstrated in the development of bifunctional oxide-zeolite catalyst concept to tackle selectivity challenge syngas chemistry. Despite general recognition on importance defect sites metal oxides for CO/H2 activation, actual structure and catalytic roles are far from being well understood. We demonstrate here that conversion can be steered along a highly active selective pathway towards light olefins via ketene-acetate (acetyl) intermediates by surface with...

Abstract Here, the photocatalytic CO 2 reduction reaction (CO RR) with selectivity of carbon products up to 100% is realized by completely suppressing H evolution under visible light (λ > 420 nm) irradiation. To target this, plasmonic Au/CdSe dumbbell nanorods enhance harvesting and produce a plasmon‐enhanced charge‐rich environment; peripheral Cu O provides rich active sites for suppresses hydrogen generation improve products. The middle CdSe serves as bridge transfer photocharges. Based...
