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.
