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.

Photocatalytic activity of TiO2 nanotube layers coated with Ag and Pt

, 2010
Thin films of anatase TiO2 nanotube arrays (TiO2 NTs) were prepared in this study. Pt and Ag were coated on the TiO2 NTs films, which intend to increase the photocatalytic activity under ultraviolet-visible (UV-vis) irradiation.

Pharmaceutical Removal with Photocatalytically Active Nanocomposite Membranes

Membranes
The advancement of pharmaceutical science has resulted in the development of numerous tailor-made compounds, i.e., pharmaceuticals, tuned for specific drug targets. These compounds are often characterized by their low biodegradability and are commonly excreted to a certain extent unchanged from the human body.
