Photo-Fenton Process over an Fe-Free 3%-CuO/Sr_0.76Ce_0.16WO₄ Photocatalyst under Simulated Sunlight.

ABSTRACT: Photo-Fenton is a promising photocatalytic technology that utilizes sunlight. Herein, an Fe-free 3%-CuO/Sr_0.76Ce_0.16WO₄ photocatalyst was synthesized to apply simulated wastewater degradation via a photo-Fenton process under simulated sunlight. The photodegradation efficiency of RhB solution over the 3%-CuO/Sr_0.76Ce_0.16WO₄ photocatalyst is 93.2% in the first 3 h; its photocatalytic efficiency remains at 91.6% even after three cycle experiments. The kinetic constant of the 3%-CuO/Sr_0.76Ce_0.16WO₄ photocatalyst is 0.0127 min^-1, which is 2.8-fold that of an intrinsic Sr_0.76Ce_0.16WO₄ sample. The experiment of radical quenching revealed that the photogene
