Novel flake PDINH/TiO2 for photodegradation of phenol under simulated sunshine irradiation

The organic-inorganic eco-friendly semiconductor photocatalysts have the ability to effectively clear away organic pollutants under daylight, so the research on their synthesis with the controllable topography to improve its solar utilization and degradation activity has drawn the attention of many scholars. In this study, the organic-inorganic nanometer flower photocatalyst PDINH/TiO 2 with enhanced photoactivity was synthesized using PDINH (perylene 3,4,9, 10-tetracarbonate diimide) as the self-assembled carrier of nano-anatase TiO 2 . The CO⋯H Hydrogen bond between PDINH and TiO 2 numerators in the In-situ self-assembly PDINH/TiO 2 Nano photocatalyst enables valid chronic electrons delocalization and thereby accelerates the migration and separation photo-generated charges, so that it has significant photocatalytic dynamic character. This experiment discussed the performance of PDINH/TiO 2 photocatalytic degradation of phenol for the first time, and the consequents evidenced that PDINH/TiO 2 nanocomposite behaved a rapid degradation of phenol (6 ppm) in 6 h under the simulated sunlight. The operation briefness and the latent of making use of the sunlight capability urged the PDINH/TiO 2 to be a notable rising star for the photodegradation of the organic pollutants in water.
