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.

Asymmetric Dual‐Electron Bridge Via Gradient Orbital Coupling for Robust Alkaline Oxygen Evolution in Low‐Iridium Water Electrolysis

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The engineered IrOx/FeEu‐NiTex composite, with ultralow Eu (0.72 at%) and Ir (0.14 at%) content, harnesses an asymmetric dual‐electron‐bridge structure (Ni 3d–O 2p–Eu 4f, Ni 3d–O 2p–Ir 5d) for gradient orbital coupling. This unique architecture delivers superior and robust alkaline oxygen evolution activity, enabling efficient low‐iridium water ...

Hydrogen Production With Water Electrolysis Technologies: Advances, Performance, and Potential Use for Low‐Gradient Combustion

Energy Science &Engineering, EarlyView.
This review links recent advances in water electrolysis with hydrogen utilization in low‐gradient combustion systems. While hydrogen eliminates direct CO2 emissions, its environmental and economic benefits depend strongly on production pathways, system‐level efficiency, and NOx mitigation through MILD/FLOX/HiTAC combustion.
