Efficient generation of sulfate radicals in Fe(ii)/S(iv) system induced by WS2 nanosheets and examined by its intrinsic chemiluminescence

Author affiliations

Abstract

In this study, the generation of more SO4˙ and strong intrinsic chemiluminescence (CL) were achieved through activating sulfite (SO32−) with ferrous ions (Fe2+) on 5 nm-thick WS2 nanosheets. The blend of CL with the Fe2+/SO32− system by introducing WS2 nanosheets not only improved the efficiency of the degradation of pollutants but also revealed the potential of using CL to study the mechanism of SO4˙-based advanced oxidation processes (SR-AOPs).
