Increasing worldwide energy demand has led to the increased combustion of fossil fuels, despite all efforts to substitute it with “green energy”. A large variety of pollutants are emitted to the atmosphere during the combustion of carbon-based fuels. Special attention is focused on soot, which is responsible for many lung (i.e., pneumonia, pneumoconiosis) and cardiovascular (i.e., arrhythmia, heart attack) diseases, as well as cancerogenic activity. The negative influence of soot on the environment (i.e., greenhouse effect by albedo) has also been confirmed.
Soot emission sources can be divided into two groups: stationary (factories, energy plants, domestic heating) and mobile (cars, planes, ships), the latter creating more problems. The most promising solution seems to be particulate filters (DPF for diesel and GPF for gasoline), combined with a catalyst. As both soot and the catalyst are in the solid state, the most important challenge for catalyst design is to ensure a high degree of contact between them, as soot/catalyst contact is a key factor in the case of activity. Three main mechanisms of catalytic soot combustion can be found in the literature—the activation of an oxygen molecule, usage of NO2 formed by the oxidation of NO, and the mobility of the catalytic phase. Many catalytic systems have been explored so far, but numerous investigations still have to be conducted in the case of basic research as well as applied studies to ultimately solve the problem of soot removal from exhaust gases.

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 papers will be 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 1800 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.
