Abstract

This study addresses the photodegradation efficiency of bisphenol A (4,4′-isopropylidenephenol, BPA) and the generation of hydroxyl radicals using the UV/TiO2 system. Photocatalysts were formed by the microwave/sol–gel method and TiO2 was prepared with anatase and rutile phases with a high surface area. The hydroxyl radicals generated by the preparation of TiO2 by a microwave/sol–gel process, and its photoactivity, exceeded those of TiO2 prepared using a sol–gel process.
