Photoelectrochemical Hydrogen Production Using TiO2/Mn‐CdS Photoanode with ZnS Passivation and CoPi as Hole Transfer Relay

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 3, March 2026.
The electrode features TiO2 as a stable UV‐absorbing substrate, Mn‐doped CdS to extend light absorption into the visible range, ZnS to prevent CdS photocorrosion, and an outer cobalt phosphate (CoPi) that catalyzes oxygen evolution, efficiently enhancing hole transfer from the photoanode to the electrolyte.

Enhanced Photocatalytic CO2 Reduction Performance by External Electric Field‐Driven Charge Separation on Interdigitated Micro‐Spacing Structure

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
An external electric field‐enhanced photocatalytic system is developed using interdigitated electrodes with 100 µm spacing to overcome the liquid‐phase limitations of traditional PEC. The induced high‐intensity electric field effectively drives the directional migration of charge carriers under low voltage. This strategy significantly suppresses charge

Effect of Ramped Oxygen Flow During Magnetron Sputtering on the Structural, Optical, and Photoelectrochemical Properties of WO3‐x Thin Films

open access: yesAdvanced Physics Research, Volume 5, Issue 3, March 2026.
A compositionally graded WO3‐x thin film was engineered through a controlled linear increase of oxygen flow during reactive magnetron sputtering. This deposition strategy yields a gradual transition from an oxygen‐deficient, conductive bottom layer to a more stoichiometric and crystalline surface layer, forming an intrinsic gradient homojunction.

Influence of Film Thickness on Screen‐Printed BiFeO3 Photoelectrodes for Nitrogen Reduction Reaction

open access: yesNano Select, Volume 7, Issue 3, March 2026.
Influence of film thickness on screen‐printed BiFeO3‐photoelectrodes for nitrogen reduction reaction. Optimization of BiFeO3‐based photoelectrodes film thickness for nitrogen conversion into ammonia by photo‐electrochemical cell. After 1 h of PEC reaction, a faradic efficiency close to 90% for ammonia at ‐0.4 V versus NHE is obtained.

Development of Coupled Electrochemical Systems for Metal Resource Recovery From Aqueous Metal‐Organic Complexes

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT The past decade has witnessed a burgeoning demand of metals for global industrial development and infrastructure. Meanwhile, the depletion of mineral resources and the environmental damage caused by wastewater discharges pose significant threats to both economic and ecological sustainability. Fortunately, metal‐containing wastewaters also hold

Coherent control of photocurrent in a strongly scattering photoelectrochemical system

open access: yes, 2016
A fundamental issue that limits the efficiency of many photoelectrochemical systems is that the photon absorption length is typically much longer than the electron diffusion length.
