Despite a suitable bandgap of bismuth vanadate (BiVO4 ) for visible light absorption, most the photogenerated holes in BiVO4 photoanodes are vanished before reaching surfaces oxygen evolution reaction due to poor charge separation efficiency bulk. Herein, new sulfur oxidation strategy is developed prepare planar with situ formed vacancies, which increases majority carrier density and photovoltage, leading record 98.2% among reported photoanodes. Upon loading NiFeOx as an cocatalyst, stable...

High-entropy alloy nanoparticles (HEANs) possessing regulated defect structure and electron interaction exhibit a guideline for constructing multifunctional catalysts. However, the microstructure–activity relationship between active sites of HEANs electrocatalysts is rarely reported.

High entropy alloys (HEAs) are a highly promising class of materials for electrocatalysis as their unique active site distributions break the scaling relations that limit activity conventional transition metal catalysts. Existing Bayesian optimization (BO)-based virtual screening approaches focus on catalytic sole objective and correspondingly tend to identify unlikely be entropically stabilized. Here, we overcome this limitation with multiobjective BO framework HEAs simultaneously targets...
