Photocatalytic degradation and rate constant prediction of chlorophenols and bisphenols by H3PW12O40/GR/TiO2 composite membrane

Photocatalysis is a promising approach to remove highly toxic and refractory aromatics pollutants. However, developing highly active photocatalyst is a long-standing challenge for pollutant degradation. This study addressed this challenge by developing GR (graphene)/TiO2 and HPW (H3PW12O40)/GR/TiO2 membranes by sol-gel method. The removal efficiencies of HPW/GR/TiO2 (the doping of 1.0% HPW) membrane for chlorophenols (including o-chlorophenol,...
