About this Research Topic
Advanced Oxidation Process (AOP) has the advantages of fast reaction rate, complete treatment, and wide application range. The strong oxidizing radicals generated by this process can oxidize and degrade organic substances into small molecules, and even eventually oxidize them into water and carbon dioxide. However, the traditional AOP technology, which uses hydroxyl radicals (-OH) as the main active substance, suffers from limited oxidation capacity, high cost, secondary pollution, and unsatisfactory treatment effect on organic wastewater. Despite the great achievements of photocatalysis in eliminating organic pollutants in the past decades, the development of energy-efficient and robust photocatalytic systems is still a great challenge.
The main challenge in this area is to elucidate the activation mechanism of persulfate by different materials, and determine the main factors affecting the radical species. Great efforts have been made to prepare various catalysts, including iron-based catalysts, cobalt-based catalysts, copper-based catalysts, manganese-based catalysts, and other metal catalysts, for the degradation of industrial wastewater by the synergistic effect of photoelectrocatalysis and peroxymonosulfate-based advanced oxidation process. The electron transfer process between organics and persulfates is another important parameter for pollutant degradation.
This Research Topic welcomes submissions on the following sub-topics:
• Synthesis of transition metal-based catalysts, non-metallic, and biochar-based materials;
• Activation mechanism of Peroxymonosulfate (PMS) or Persulfate (PS) by oxygen vacancy, transition metal ion, visible light irradiation, Lewis acid, Lewis base, or ionizing radiation;
• Free radical or non-free radical processes;
• Synergistic effects of photoelectrocatalysis and advanced oxidation technology based on persulfate activation on the treatment of organic pollutants in water or industrial wastewater;
• Study on degradation kinetics of organic contaminants.
