Bandgap‐Engineered AlGaAs/GaAs Heterostructures for Wavelength‐Selective Dual‐Polarity Photoelectrochemistry

Advanced Functional Materials, Volume 36, Issue 55, 9 July 2026.
Bandgap‐engineered AlGaAs/GaAs heterostructures exhibit wavelength‐selective dual‐polarity photoelectrochemistry, switching from photocathodic to photoanodic response depending on excitation wavelength. The polarity transition is governed by band‐selective absorption, built‐in electric‐field‐driven carrier transport, and interfacial charge‐transfer ...

Precise Electrodeposition of Mo6‐Cluster Thin Films: Mechanistic Pathways to Ambipolar Photoelectrodes With Tailored Microstructure

ChemPhotoChem, Volume 10, Issue 7, July 2026.
Homogeneous, crack‐free photoelectrodes were prepared by electrodeposition (ED) of [{Mo6Ii8}Ia6]2− clusters. This process enables unprecedented control over film thickness and microstructure, resulting in increased photoconductivity compared to films obtained by electrophoretic deposition. The films exhibit ambipolar behavior and a quasi‐pinned mid‐gap

Pure Water‐Fed Photoelectrochemical Water Splitting Using a Porous WO3 Electrode Surface‐Modified With Perfluorosulfonic Acid Ionomer

ChemSusChem, Volume 19, Issue 11, 15 June 2026.
This study demonstrates a proton exchange membrane (PEM)‐based photoelectrochemical (PEC) system for pure‐water splitting using a porous tungsten oxide (WO3) photoanode coated with a perfluorosulfonic acid (PFSA) ionomer. Proton transport at the WO3 surface is the rate‐limiting step for oxygen evolution, and the ionomer surface modification is ...

PEC‐DFM Hybrid‐Sensor Based on Nanoparticle‐Resolved Estimation for Sensitive and Reversible Glucose Monitoring

Advanced Science, Volume 13, Issue 31, 4 June 2026.
Abstract The accurate detection of glucose in wound exudate is critically important for monitoring chronic wound healing. While photoelectrochemical (PEC) sensors are widely used, they often suffer from material degradation caused by redox reactions during operation. Herein, we introduce a dark‐field microscopy (DFM) setup integrated with a PEC system,
