Overlooked role of nitrogen dopant in carbon catalysts for peroxymonosulfate activation: Intrinsic defects or extrinsic defects?

Shengjiong Yang et al.

Summary: The study uncovered the role of nitrogen dopant in carbon catalysts, where nitrogen is partially evaporated at high temperature to form topological intrinsic defects, promoting the activation of peroxymonosulfate and organic degradation through an electron-transfer mechanism. The findings suggest that surface-activated PMS complex is the main reactive oxidation species for organic degradation.

Understanding oxygen-deficient La2CuO4-δ perovskite activated peroxymonosulfate for bisphenol A degradation: The role of localized electron within oxygen vacancy

Hanxiao Chen et al.

Summary: An A(2)BO(4)-type oxygen-deficient perovskite (La2CuO4-delta, LCO) shows superior low-temperature reducibility and more abundant oxygen vacancies (OVs) compared to CuO oxide, and was successfully used in peroxymonosulfate (PMS) activation for more than 96% BPA removal within 60 mM over a wide pH range. The activation mechanism involves surface Cu(II)/Cu (I) redox couple, lattice oxygen (O2-)/O-2, and direct activation of PMS by OVs with localized electrons.
