Abstract Single‐component electrocatalysts generally lead to unbalanced adsorption of OH − and urea during oxidation reaction (UOR), thus obtaining low activity selectivity especially when oxygen evolution (OER) competes at high potentials (>1.5 V). Herein, a cross‐alignment strategy in situ vertically growing Ni(OH) 2 nanosheets on 2D semiconductor g‐C 3 N 4 is reported form hetero‐structured electrocatalyst. Various spectroscopy measurements including experiments indicate the existence enhanced internal electric field interfaces vertical nanosheets, favorable for balancing intermediates. This heterojunction electrocatalyst shows high‐selectivity UOR compared pure , even V) large current density. The computational results show could steer increase urea, efficiently avoiding poisoning strongly adsorbed active sites. A membrane electrode assembly (MEA)‐based electrolyzer with anode operate an industrial‐level density 200 mA cm −2 . work paves avenue designing high‐performance by cross‐alignments components.

Abstract Transition metal chalcogenides (TMCs) are widely used in photocatalytic fields such as hydrogen evolution, nitrogen fixation, and pollutant degradation due to their suitable bandgaps, tunable electronic optical properties, strong reducing ability. The unique 2D malleability structure provides a pre‐designed platform for customizable structures. introduction of vacancy engineering makes up the shortcomings photocorrosion limited light response greatest support TMCs terms kinetics thermodynamics photocatalysis. This work reviews effect on performance based semiconductor TMCs. characteristics strategies summarized, development photocatalysis materials energy conversion, degradation, biological applications is reviewed. contribution vacancies range charge transfer also discussed from perspective manipulation. Vacancy not only controls optimizes TMCs, but improves transfer, surface properties. synergies between atomic doping, other vacancies, heterojunction composite techniques detail, followed by summary current trends potential expansion.

The conversion of solar energy into hydrogen using photocatalysts is a pivotal solution to the ongoing and environmental challenges. In this study, inverse opal (IO) ZnIn2S4 (ZIS) with varying pore sizes synthesized for first time via template method. experimental results indicate that constructed has unique photonic bandgap, its slow photon effect can enhance interaction between light matter, thereby improving efficiency utilization. voids 200 nm (ZIS–200) achieved highest production rate 14.32 μ mol h−1. normalized specific surface area five times higher than broken structures (B–ZIS), as red edge ZIS–200 coupled intrinsic absorption ZIS. This study not only developed an approach constructing multi–metallic sulfides, but also provides new strategy enriching efficient ZnIn2S4–based evolution from water.
