A low-cost sensitizer based on a phenolic resin for charge-transfer type photocatalysts working under visible light

-Guan Zhang and Wonyong Choi*

Phenolic resin (denoted as PR) was used as an economical sensitizer of titania to achieve efficient visible light photocatalytic activity. Through the surface complexation of PR with TiO2, we demonstrate that the complexed PR layer sensitizes TiO2 under visible light through the ligand-to-metal charge transfer (LMCT) mechanism.
