Engineering Bilayer Tandem Catalysts on Si‐Based Photocathodes for High‐performance CO2 Reduction to Produce Methane

Advanced Materials, Volume 38, Issue 15, 12 March 2026.
A Cu/Ag‐Cu bilayer tandem catalyst is designed for a pyramid‐structured p‐Si photocathode, creating multiple and functionally distinct interfaces tailored to specific reaction steps and intermediate stabilization. This Cu/Ag‐Cu‐decorated p‐Si photocathode exhibits both high photocurrent and good selectivity for photoelectrochemical CO2 reduction to CH4.

Spontaneously formed porous and composite materials [PDF]

, 2010
In recent years, a number of routes to porous materials have been developed which do not involve the use of pre-formed templates or structure-directing agents. These routes are usually spontaneous, meaning they are thermodynamically downhill.

Visible Light‐Activated ZnO@CuO Coaxial Nanofibers Enhance Infected Skin Wound Healing Through Construction of p‐n Heterojunctions

Advanced Science, Volume 13, Issue 16, 18 March 2026.
Coaxial ZnO@CuO nanofibers activated by visible light generate ROS through enhanced photocatalytic reactions driven by improved electron hole separation in the heterojunction. This strategy enables rapid antimicrobial activity and early infection control, thereby promoting the healing of MRSA infected and diabetic wounds with biosafe and easily ...

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

Advanced 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.
