Special Issue Information
Dear Colleagues,
The global environmental protection has been a hot topic in research works over the last two decades. The European Commission presented the so-called Green Deal in December 2019, also known as the Green Pact, which is a set of policies aimed at making Europe climate-neutral by 2050. The plan is to reduce greenhouse gas production by at least 50% compared to 1990 levels, and to have zero pollution by 2050, whether it is soil, air, or water pollution.
The main air pollutants are PM (particulate matter), SO2, NH3, NOx, volatile organic compounds (VOCs), and CH4. Abatement of volatile organic compounds (VOCs) and carbon monoxide (CO) in waste gases is an important task in the areas of environmental protection and odor control. Catalytic combustion is a competitive abatement technique for VOC removal, especially when the organics cannot be recycled or are present in low concentrations. Since catalytic incineration takes place at temperatures much lower than those required for thermal incineration, this results in lower costs and low NOx formation.
The major component of particulate matter, soot, can pose a significant hazard to humans and the environment. Soot particles are formed from the incomplete combustion of diesel fuel under high-temperature and oxygen-deficient conditions. The harmful substances, such as sulfates and polycyclic aromatic hydrocarbons, adsorbed on the surface of soot particles not only pollute the atmospheric environment but also pose a direct threat to human health. Therefore, it is urgent to limit the emission of soot particles in diesel engine exhaust. Diesel filters are used in exhaust systems to reduce the amount of soot emitted into the environment. Although soot particles are successfully removed by these filters, they still build up and cause increased backpressure, which impairs engine performance and fuel efficiency. There are two ways to regenerate diesel filters: passive regeneration and active regeneration. By using a diesel oxidation catalyst on diesel filters, the passive regeneration approach lowers the activation energy of soot oxidation and, in effect, lowers the soot oxidation temperature.
In this Special Issue of Catalysts, we invite authors to submit original research papers focused on the synthesis, characterization, modification and application of catalysts in different industrial and laboratory processes for VOC and soot oxidation. Articles related to quantum chemical and kinetic modeling are also welcome.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Catalysts is an international peer-reviewed open access monthly 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 2200 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.
