Phosphorous nitride dots induced efficient advanced oxidation with intrinsic chemiluminescence for organic pollutant degradation

Abstract

In this work, we introduced new metal-free catalysts, phosphorus nitride dots (PNDs), into an environmentally friendly H₂O₂–SO₃²⁻ system to generate abundant reactive oxygen species (O2˙⁻, ˙OH and SO4˙⁻) with strong intrinsic chemiluminescence (CL). The excellent catalytic ability of PNDs not only improved the degradation efficiency of organic pollutants, but also provided a promising prospect for deeply probing the mechanism of advanced oxidation processes (AOPs) by combining with CL.
