Novel Highly Active Visible-Light-Induced Photocatalysts Based on BiOBr with Ti Doping and Ag Decorating

Visible-light-induced BiOBr photocatalysts with Ti doping and Ag decorating were prepared by three methods (chemical reduction, photoreduction, and thermal reduction). Compared to the tannin acid reduction and photoreduction, the solvothermal reduction method was relatively simple and efficient, and...

Description
Summary:Visible-light-induced BiOBr photocatalysts with Ti doping and Ag decorating were prepared by three methods (chemical reduction, photoreduction, and thermal reduction). Compared to the tannin acid reduction and photoreduction, the solvothermal reduction method was relatively simple and efficient, and Ag doping and loading simultaneously occurred. The as-prepared 3% Ag/Ti-dope BiOBr photocatalysts exhibited the flowerlike microsphere structures that assembled by nanoplates, and showed higher photocatalytic activity and excellent durability.
