Dihydroxyanthraquinones as stable and cost-effective TiO2 photosensitizers for environmental and biomedical applications
Abstract
Cost-effective dihydroxyanthraquinones can sensitize TiO2 to visible light. 1,5-, 1,8-dihydroxyanthraquinones are the most active and stable modifiers of TiO2. Materials exhibit activity against Gram(+), Gram(‑) bacteria, and fungi. Addition of KI in PDI tests causes a superb bactericidal and fungicidal activity. TiO2 modified with dihydroxyanthraquinones can photogenerate HO and 1O2.
