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.

Abstract Efficient photocatalytic water splitting for hydrogen production relies not only on semiconductor design but also the configuration of interfacial molecules and mass transfer processes, which remain underexplored. This study unveils a multidimensional synergy mechanism involving infrared light-thermal-electron-structure interactions in SrTiO3-based systems. Systematic characterization using in-situ Raman spectroscopy revealed cooperative between infrared-induced electronic excitation thermal activation Infrared radiation facilitates phonon-assisted indirect bandgap transitions SrTiO3 while generating localized gradients. Complementary situ electron paramagnetic resonance analysis demonstrated that thermally activated interface environment enhances d-orbital spin activity Co2+ co-catalysts, critically promotes proton-coupled dynamics. Through synergistic exploitation light-thermal-electronic-structural coupling effects, we realized remarkable enhancement solar-to-hydrogen conversion efficiency (1.58% vs. benchmark 0.82%). Thermodynamic kinetic analyses further confirmed existence dual pathways. These findings provide mechanistic understanding theoretical foundation optimizing systems splitting.

The rise in global temperatures and environmental contamination resulting from traditional fossil fuel usage has prompted a search for alternative energy sources. Utilizing solar to drive the direct splitting of water hydrogen production emerged as promising solution these challenges. Covalent organic frameworks (COFs) are ordered, crystalline materials made up molecules linked by covalent bonds, featuring permanent porosity wide range structural topologies. COFs serve suitable platforms solar-driven produce hydrogen, their building blocks can be tailored possess adjustable band gaps, charge separation capabilities, porosity, wettability, chemical stability. Here, impact interface context photocatalytic reaction is focused propose strategies enhance performance photocatalysis. In particular, how hybrid interfaces affect focused.

Abstract We demonstrate an electrostatic confinement‐induced charge transfer pathway in a supramolecular photocatalyst comprising of ionic covalent organic framework (COF) and cationic metal complexes. The dynamic interactions not only attract cations around the COF to accept photogenerated electrons, but also allow for retention homogeneous catalytic characters complexes, making subtle balance. Accordingly, confinement effect facilitates forward electron from photoexcited Co complex, realizing remarkable photocatalytic CO 2 reduction performance. Its efficiency is far superior counterparts with Van‐der‐Waals or hydrogen bonding interactions. This work presents insight enhancing systems, provides effective approach construction highly efficient photocatalysts.
