Charge‐Polarized Ni─S4 Single‐Atom Sites Drive Selective Photoreforming of Poly(lactic acid) to Lactate and Hydrogen

Advanced Functional Materials, EarlyView.
Atomically dispersed Ni–S4 sites on CdS nanorods induce interfacial charge polarization, directing photogenerated electrons to H2 evolution and holes to selective ester‐bond cleavage of poly(lactic acid). Without sacrificial reagents, this charge‐coupled system produces lactate while suppressing overoxidation, achieving an H2 evolution rate of 41.74 ...

Photoinduced Interfacial Electronic Modulation in Fe2O3‐BiVO4 Heterostructures for Enhanced Photo‐Assisted Zn‐Air Batteries

Advanced Functional Materials, EarlyView.
Light irradiation activates the Fe2O3‐BiVO4 heterostructure, enabling efficient solar‐electrochemical coupling in zinc‐air batteries. The built‐in electric field drives directional charge separation, guiding photoelectrons toward oxygen reduction sites and accumulating holes for oxygen evolution, thereby reducing polarization and enhancing discharge ...
