Abstract
The aim of this study is to evaluate phenol degradation capability of silver modified titanium dioxide nanomaterial on bentonite support (Ag-TiO2/Bent). The material was synthesized as photocatalyst by adding Ag-TiO2 sol into bentonite suspension. The experimental results revealed that photooxidation activity of Ag-TiO2/Bent was greatly higher than that of Ag-TiO2 and TiO2/Bent. The phenol removal efficiency was 23.25%, 35.41% and 98.94% for Ag-TiO2, TiO2/Bent and Ag-TiO2/Bent, respectively. The dispersion of silver modified TiO2 on bentonite support significantly enhances photocatalytic activity under solar radiation due to surface plasmon resonance formation and prevention of anatase-to-rutile phase transformation.
