Preparation of fly ash supporting nano-TiO2 composite photocatalyst by a wet mechanical grinding method

Abstract

In this study, nano-TiO2 and FACs were used to prepare a composite photocatalyst (FACs-TiO2) by a wet mechanical grinding method. FACs-TiO2 was fabricated by using nano-TiO2 that was uniformly loaded on the surface of FACs, and the TiO2 particles were 20–30 nm in size. The degradation effect of FACs-TiO2 was comparable to that of commercial nano-TiO2 (P25). The reduction in TiO2 dosage in FACs-TiO2 could markedly reduce TiO2 application costs; thus, it shows promise for practical application.
