Defect‐Driven Charge Separation in Ba‐Doped SrTiO3: Correlating Photoelectrochemical Performance With Dye‐Selective Photocatalysis

Advanced Materials Interfaces, EarlyView.
Ba‐doped SrTiO3 perovskites establish a direct correlation between photoelectrochemical activity and photocatalytic performance. Optimized Ba0.5Sr0.5TiO3 exhibits enhanced charge separation, photocurrent generation, and visible‐light‐driven dye degradation through defect‐induced oxygen vacancies and lattice distortion.

Band Alignment and Composition of the Buried TiO2/GaInP Interface

Advanced Materials Interfaces, EarlyView.
Buried TiO2$\text{TiO}_2$/GaInP interfaces formed by mild plasma‐enhanced ALD are shown to be largely insensitive to the initial GaInP surface condition. Angle‐dependent photoelectron spectroscopy reveals similar interfacial chemistry and band alignment for phosphorus‐rich and naturally oxidized surfaces, demonstrating a robust pathway for reproducible

Omnidirectional Ultra‐Broadband Cu/TiO2 Metasurface Absorbers for High‐Efficiency Solar Thermal Conversion and Photothermal Plasmon‐Driven Catalysis

Advanced Optical Materials, EarlyView.
Metasurface shows selective solar–thermal energy conversion with high‐activity solar/laser‐driven chemistry. The breakthrough is co‐designing broadband FP‐cavity + plasmonic LSPR/SLR resonances in an ultra‐thin metamaterial so that it not only harvests the most efficient proportion of solar radiation but also suppresses mid and IR emissivity. Moreover,
