Abstract The coupling of semiconductor (SC) and transition metal oxyhydroxide (TMOOH) is a promising approach for solar fuel production. However, the inevitable interfacial charge recombination sluggish oxygen evolution reactions severely hinder application photoelectrochemical (PEC) device. This study demonstrates an innovative polarization strategy that simultaneously enhances both long‐range transfer surface catalytic reaction dynamics through rational construction CoO x /MnO heterointerface in SC/TMOOH system. Kelvin probe force microscopy, situ ultraviolet/visible spectroelectrochemistry, density functional theory calculations indicate tunable Co δ− Mn δ+ can affect influences TMOOH/electrolyte interfaces, primarily inducing accelerated ( K h ) diminishing adsorption oxygen‐containing intermediates. As anticipated, BiVO 4 /CoO /FeNiOOH exhibits impressive photocurrent 6.75 mA cm −2 at 1.23 V RHE , along with superior photostability. Furthermore, smart also be harnessed /CeO photoanode. provides novel design optimal photoanodes PEC water splitting.

Hydrogen and oxygen serve as energy carriers that can ease the transition of due to their high densities. Nonetheless, production processes entail development efficient low-cost storage conversion technologies. In this regard, photoelectrocatalysts are materials based on photoelectronic effect where electrons holes interact with H2O, producing H2 O2, in some cases, is achieved acceptable efficiency. Although there several reviews topic, most them focus traditional semiconductors, such TiO2 ZnO, neglecting others, those non-noble metals organic ones. Herein, semiconductors like CdSe, NiWO4, Fe2O3, others have been investigated compared terms photocurrent density, band gap, charge transfer resistance. addition, brief review aims discuss mechanisms overall water-splitting reactions from a photonic point view subsequently discusses engineering material synthesis. Advanced composites also addressed, WO3/BiVO4/Cu2O CN-FeNiOOH-CoOOH, which demonstrate efficiency by delivering densities 5 mAcm−2 3.5 mA cm−2 at 1.23 vs. RHE, respectively. Finally, authors offer perspectives list main challenges experience developing semiconductor-based applied fields. manner, provides advances these topics, used references for new directions designing active photoelectrocatalytic water splitting.

In this study, we integrate medium-entropy cocatalysts (MECs), composed of four elements─Fe, Ni, Co, and Cr─into nanostructured hematite (Fe2O3) thin films using a laser deposition process to enhance the photoelectrochemical (PEC) water splitting performance. The MEC-integrated (MEC-Fe2O3) photoanodes exhibit remarkable improvements in oxidation photocurrent, achieved through enhanced charge injection efficiency negatively shifted onset potential compared bare Fe2O3. Multiphysics modeling elucidates laser-induced MEC formation mechanism by estimating temperature increase changes energy band structure carrier concentrations. Furthermore, time-resolved photoluminescence (TRPL) studies unveil that layer extends lifetime photogenerated carriers, leading an overall enhancement process. This work highlights promising laser-deposited as viable strategy boost PEC applications.
