Abstract

We studied the photocatalytic activity of Ti-montmorillonite. The highest activity was found for a Ti/bentonite ratio of 10 mmol/g, prepared using HCl and calcined by microwaves. This mixture is less active than TiO2 P-25 for 4-chlorophenol removal in water, but more active for methanol removal in air.
