State of the Art of Catalytic Oxidation/Reduction of Pollutants Removal

Dear Colleagues,

The pervasive challenge of environmental pollution, encompassing air, water, and soil matrices, demands advanced and efficient remediation technologies. Persistent and emerging contaminants, from volatile organic compounds and nitrogen oxides to pharmaceuticals and microplastics, threaten ecosystem integrity and human health. Catalytic oxidation and reduction technologies stand at the forefront of advanced abatement strategies, offering the potential for high-efficiency, selective, and often energy-tunable destruction or transformation of pollutants into benign substances. The core of this field lies in the rational design of high-performance, stable, and cost-effective catalysts, coupled with a deep understanding of reaction mechanisms and pathways. Current research is vigorously pursuing innovations in catalytic materials, process intensification, and the integration of complementary technologies to address complex real-world emission and discharge streams.

This Special Issue on “State of the Art of Catalytic Oxidation/Reduction of Pollutants Removal” seeks high-quality research articles, reviews, and short communications that showcase cutting-edge developments and future directions in this critical area. Topics include, but are not limited to, the following:

• Design and synthesis of novel catalytic materials (e.g., single-atom catalysts, nano-architectured materials, MOFs, spinels, non-precious metal catalysts) for environmental applications.
• Catalytic oxidation processes: VOC combustion, CO oxidation, catalytic ozonation, peroxymonosulfate/persulfate activation, photocatalytic/electrocatalytic degradation.
• Catalytic reduction processes: NOx reduction (SCR, CO-SCR), CO2 hydrogenation, catalytic hydrogenation of organic pollutants, reduction of halogenates and oxyanions.
• Mechanistic investigations using in situ/operando characterization, theoretical calculations, and probe reactions to elucidate active sites and pathways.
• Dual-function or bifunctional catalysts for simultaneous oxidation and reduction.
• Catalytic processes for indoor air purification, industrial off-gas treatment, and vehicle emissions control.
• Catalytic remediation of contaminated soils or groundwater (e.g., in situ chemical oxidation/reduction).
• Stability, deactivation resistance, regeneration strategies, and longevity of environmental catalysts.
• Integrated process design combining catalysis with adsorption, plasma, or biological treatment.
• Pilot-scale studies, reactor design, and techno-economic or lifecycle analysis for sustainable implementation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Processes is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
