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).
