Sn4+ doped FeOCl has been successfully synthetized as a sunlight-driven photo-Fenton catalyst, which shows that the catalytic activity of Sn4+/FeOCl (1.08% Sn4+ in the Sn4+/FeOCl) is a factor of 11.8 time higher than that of FeOCl. The doping of Sn4+ in FeOCl increases the optical adsorption and surface area of FeOCl. The decreased chemical bond strength of Fe-Cl in Sn4+/FeOCl effectively increases the number of exposed active sites (Fe-site and Sn-site), which boosts the production of center dot OH radicals. The Sn-site shows higher catalytic activity than Fe-site. A synergistic mechanism for Sn4+/FeOCl is proposed for the enhanced catalytic performance. (C) 2018 Elsevier B.V. All rights reserved.
