Photocatalytic Oxidation, Materials Studies, Photochemistry Analysis in Organic Pollutants under Sustainable Environmental Governance

Dear Colleagues,

Photocatalytic technology has emerged as a potential approach for effluent treatment. Photocatalytic technology utilizes solar energy to drive photocatalysts and realize the decomposition of water to produce free radicals with highly oxidative and reductive properties. The free radicals can effectively remove organic pollutants without generating secondary pollution. Additionally, the photocatalyst has the advantage of being recyclable as well. Therefore, the key to achieving commercial industrialization lies in the development of optimal photocatalysts that exhibit superior efficiency, significant specific surface area, maximum utilization of solar energy, and recyclability.

The aim of this topic is to prepare visible light-responsive photocatalysts or ultraviolet light-responsive photocatalysts, or to prepare heterojunction photocatalysts, precious metal-doped composite photocatalysts, and composite photocatalysts loaded with double defects. Using advanced oxidation technology and novel monocrystalline photocatalysts (or novel composite photocatalysts), photocatalytic oxidative degradation of organic pollutants in wastewater is carried out under sunlight irradiation, or under ultraviolet light illumination, or under visible light irradiation. It mainly degrades organic pollutants such as rhodamine B, indigo and methyl blue in printing and dyeing wastewater, organic pollutants such as methyl parathion, phoxim and pentachlorophenol in pesticide wastewater, and organic pollutants such as norfloxacin, enrofloxacin, spiramycin and other antibiotics in pharmaceutical wastewater. The degradation removal rates of above organic pollutants and the removal rate of the total organic carbon should be analysed and summarized. The intermediates and their mass to charge ratio during photocatalytic degradation of above organic pollutants should be examined. The degradation pathways of above organic pollutants should be given, and the capture agent experiments should be provided to analyse the comparison of the oxidation abilities of superoxide anion, hydroxyl radical and positive hole. The degradation mechanism of above organic pollutants should be revealed.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following: Novel photocatalysts, mulriple photocatalysts, heterogenous junction catalyst, photocatalytic oxidation of organic pollutants, photochemistry analysis, property characterization, degradative pathway of organic pollutants, degradation mechanism, photocatalysts in environmental remediation, wastewater treatment, removal of gaseous pollutant, removal of toxic organic pollutant, auto purification by using photocatalysts, disinfection treatment by using photocatalysts, odor treatment by using photocatalysts, visible light irradiation, Hydrogen production by water splitting, ustainable environmental protection.

I/We look forward to receiving your contributions.
