Abstract:

In the degradation process of organic pollutants using activated persulfate oxidation technology, it is very important to develop new activation technology which is economical, efficient and safe, and it has become a research hotspot. In recent years, carbon materials, with their unique advantages and promising application prospects, have been widely concerned, and are expected to become a new generation of green catalysts for advanced oxidation technology. In this paper, the latest research progress on the application of various carbon-based materials including activated carbon, different types of biochar, surface modified carbon materials, heteroatom modified carbon materials, and metals and metal oxides loaded carbon materials for persulfate activation and carbon materials coupling with other technologies to activate persulfate to degrade organic pollutants are deeply reviewed. In addition, the operating cost of activated persulfate oxidation technology with carbon materials and other different methods is discussed. Finally, the current challenges and future development direction of carbon materials in persulfate based advanced oxidation technology are put forward. This review may provide a reference for the further popularization and application of carbon materials on catalyzing persulfate advanced oxidation reaction to degrade organic pollutants.

Key words: persulfate advanced oxidation technology, carbon materials, catalyst activation, oxidation, radicals, organic pollutants
