Special Issue Information

Dear Colleagues,

The overall focus, scope, and purpose of this Special Issue is as follows:

Overall focus: catalytic elimination of environmental pollutants—including small-molecular organic acids and other macromolecular organics present in water environment.

Scope: A comprehensive understanding of advanced oxidation decontamination techniques, especially for industrial applications. All aspects of the design, preparation, characterization, and regeneration of various green and novel catalysts, which can be derived from biomass, transition metals, etc. In particular, the conversion of environmental waste into environmentally friendly catalysts for renewable use is encouraged. Scientific insight into the degradation paths of pollutants and the application of interfacial catalytic oxidation processes in solving environmental challenges are also encouraged.

Purpose: Use a variety of practical technologies to solve existing environmental pollution problems. The combination of adsorption separation and oxidation technology for the efficient removal of macromolecular organic micropollutants is highly regarded.

Contextual Relevance: Discuss how the topics covered align with current trends and gaps in environmental catalysis research. Highlight the significance of addressing pollutants from both stationary and mobile sources, as well as advancements in catalyst development for clean energy production.

Literature Review: Summarize key findings from relevant studies in catalytic pollution control, clean energy production, photocatalytic processes, and biomass transformation. Emphasize areas where new catalytic routes or technologies can make a significant impact.

Future Directions: Suggest future research directions based on gaps identified in the literature and emerging challenges in environmental catalysis. This could include exploring new catalyst materials, improving catalytic efficiency, or integrating catalytic processes into broader environmental management strategies.

Catalytic ozonation with metal oxides is of interest for advanced water treatment technology. The amount of active oxygen-containing radicals produced is a primary objective of this process. Fe2O3 is a widely used catalyst because of its high performance. In this study, Fe2O3/SBA-15 was synthesized and characterized. The results revealed that Fe2O3/SBA-15 was a nano-/mesoporous material with high-order hexagonal array structures and exhibited greater catalytic performance than Fe2O3 in ozonation processes. To investigate the role of the Fe2O3/SBA-15 surface in O3 decomposition, the kinetic constant was measured, and the interfacial reactions were discussed. Compared with Fe2O3, Fe2O3/SBA-15 significantly increased the formation of hydroxyl radicals (•OH) and the efficient utilization of O3 in the catalytic O3 decomposition process. The SBA-15 support decreased the O3 self-decomposition rate during catalytic ozonation with Fe2O3/SBA-15, which resulted in increased formation of •OH via the reaction between O3 and Fe2O3. From a practical point of view, Fe2O3/SBA-15 is an efficient green ozonation catalyst for water treatment. Full article
