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.

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

EcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

Oxygen Vacancy‐Engineered S‐Scheme FeOOH/Ov‐BiVO4 Heterojunction: Interfacial Charge Dynamics Optimization and Pathogenic Polypeptide Aggregates Degradation

EcoEnergy, EarlyView.
By integrating interfacial oxygen vacancies and cone‐shaped FeOOH, a highly efficient S‐scheme FeOOH/Ov‐BiVO4 photoanode was constructed. This dual‐strategy significantly accelerates charge transfer and enhances reactant adsorption, achieving outstanding photoelectrochemical degradation of pathogenic amyloid β‐polypeptide aggregates.
