Abstract Exciton effects caused by the inherent dielectric confinement in 2D material carbon nitride (CN) severely limit transfer of photogenerated carriers and selective generation free radicals. Herein, a homo‐hetero double junction coupling strategy is reported to address these challenges. Ternary homojunction (HCCN) functionalized with cyano cyanamide groups constructed built‐in electric field that efficiently separates electron–hole into different structural units, thereby reducing reverse charge recombination weakening exciton effects. The introduction α‐Fe 2 O 3 (FO) subsequently constructs catalyst FO/HCCN 127 times stronger than HCCN, which promotes directional migration after dissociation achieves ≈100% ·O − from . These results suggest 99.6% removal tetracycline within 20 min, degradation rate 12 46 higher FO/CN respectively. In addition, system shows excellent stability cyclability real‐life light experiments trace organic contaminant removal. This opens up new avenues precisely controlling

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.

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.
