Mesoporous Titania-Silica nanocomposite as an effective material for the degradation of Bisphenol A under visible light

Mesoporous Titania-Silica nanocomposite as an effective material for the degradation of Bisphenol A under visible light

A simple and very effective method is proposed for the removal of Bisphenol A (BPA) under visible light using mesoporous TiO2-SiO2 nanocomposite. The material was characterized using FTIR, XRD, DRS, XPS, FESEM, HRTEM, and BET techniques. The photo degradation efficiency of TiO2-SiO2 compared with ba...
