“…Photocatalysis, a typical advanced oxidation technique, has become the route with the most potential to conquer these intensifying environmental problems via the utilization of solar light [9,10,11]. Hence, various semiconductors, such as g-C 3 N 4 , TiO 2 , ZnS, ZnO, CuS, and MoS 2 , have been confirmed as cost-effective photocatalysts for the heterogeneous photocatalytic purification of polluted water [12,13,14,15,16,17]. Due to their wide band gap, nontoxicity, and high stability, cerium dioxide (CeO 2 ) and TiO 2 have been widely applied in photocatalytic reactions [18,19,20].…”
