Special Issue Information

Dear Colleagues,

Research in recent decades has shown the contamination of many water, soil, and air environments by anthropogenic organic compounds due to waste gas and wastewater discharge and inappropriate waste disposal. The effective removal of various organic pollutants is a major challenge in water, soil, and air treatment. Advanced chemical technologies (ACTs) have been considered a promising option because the highly reactive radicals such as hydroxyl, sulfate, chlorine, and carbon-centered radicals generated in ACTs can effectively oxidize a broad range of organic pollutants. Based on the above considerations, submissions to this Special Issue on “Advanced Chemical Technologies for Organic Pollutant Treatment” are welcome in the form of original research articles and reviews that highlight the state of research in wastewater treatments, soil remediation, and air purification.

This Special Issue will focus on studies on the mechanistic understanding, development, and implementation of ACTs for the removal of organic pollutants in water, soil, and air treatment, including ozone-, H2O2-, persulfate-, and peracetic acid-based ACTs, electricity-driven ACTs, and photocatalytic ACTs.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Chemical oxidation;
  • Fenton-like;
  • Ozone;
  • Hydrogen peroxide;
  • Persulfate;
  • Peracetic acid;
  • Electrochemical oxidation;
  • Photocatalysis;
  • Organic contaminants.

I look forward to receiving your contributions.

Dr. Lingshuai Kong

Ce–based catalysts exhibit a poor stability and activity in chlorinated volatile organic compound (Cl–VOC) oxidation due to their rapid Cl poisoning. Herein, phosphotungstic acid (HPW) was coated on CeO2 to improve its activity and stability for chlorobenzene (CB) oxidation. The HPW coating not only promoted CB adsorption onto CeO2, but also provided Brønsted acid sites to CeO2 for Cl species removal as HCl, thus avoiding Cl poisoning. Hence, a synergistic effect of CeO2 and HPW on HPW/CeO2 was observed, resulting in superior CB oxidation activity and stability. Additionally, to improve the sulfur resistance of the catalyst, the inhibition mechanism of SO2 on CB oxidation by HPW/CeO2 was explored. HPW/CeO2 was prone to sulfation due to the formation of Ce2(SO4)3 from the reaction of SO2 and CeO2. Thus, the oxidation ability of HPW/CeO2; the amount of adsorption sites for CB adsorption; and the amounts of Ce4+ bonded with O2−, lattice oxygen species, and adsorbed oxygen species were decreased by SO2. Meanwhile, SO2 competed with CB for the adsorption sites on HPW/CeO2. Therefore, CB oxidation by HPW/CeO2 was remarkably restrained by SO2. The present work promotes further work on Cl–VOC removal by Ce-based catalysts for anti-SO2 poisoning modification in the future. Full article
