Synergistic interactions of Cu and N on surface altered amorphous TiO 2 nanoparticles for enhanced photocatalytic oxidative desulfurization of dibenzothiophene

Amorphous TiO 2 (AT) nanoparticles were prepared by a simple sol–gel method and subsequent incorporation with 5–20 wt% copper via an electrochemical method in the presence of tetraethylammonium perchlorate gave an active CuO/TiO 2 (CAT) photocatalyst.
