Dual p‐n Heterojunction and Photothermal Conversion Synergy Endows NiFe‐LDH/CoS/BiVO4 Photoanodes With Enhanced Photoelectrocatalytic Performance

Carbon Energy, EarlyView.
A novel p‑n heterojunction NiFe‑LDH/CoS cocatalyst is rationally assembled on BiVO4 to yield dual p‐n heterojunction photoanodes. Benefiting from the intrinsic photothermal effect of CoS, the obtained NiFe‐LDH/CoS/BiVO4 photoanodes accelerate interfacial charge separation and transportation, optimizes sluggish surface OER kinetics, and achieves ...

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Nitrogen‐Site Isomerism Unlocks Exciton Dissociation in Vinylene‐Linked COF‐Based Photocatalysts

EcoEnergy, EarlyView.
Two regioisomeric vinylene‐linked covalent organic frameworks (COFs) constructed from diazine units with different nitrogen positions are developed for photocatalytic hydrogen evolution reaction (HER). Although structurally similar, the isomeric COFs exhibit distinct electron distribution and charge‐separation behaviors, leading to a more than twofold ...

Metal‐Organic Framework‐Templated Construction of Internal Electric Field and S‐Vacancy Defect‐Engineered S‐Scheme Heterojunction for Enhanced Photocatalytic Hydrogen Evolution

EcoEnergy, EarlyView.
A Bi2S3@ZnIn2S4 heterojunction with abundant sulfur vacancies was fabricated through MOF‐templated in situ synthesis. DFT calculations and experiments confirm the presence of an internal electric field (IEF) and S‐scheme charge transfer. The optimized catalyst shows a superior H2 evolution rate of 5.13 mmol·h−1 g−1 under visible light, which is 11.7 ...

Constructed Red Phosphorus/BiVO4 S‐Scheme Heterojunction for Efficient Photocatalytic Overall Water Splitting

EcoEnergy, EarlyView.
An S‐scheme red phosphorus/BiVO4 heterojunction is presented, where red phosphorus served as the water reduction site, and BiVO4 functioned as the water oxidation site. Because it has a built‐in electric field that helps charge transfer and separation, red phosphorus/BiVO4 works very well in the photocatalytic overall water splitting process.
