New Catalysts and Catalytic Technologies for Diesel Soot Emission Reduction

Dear Colleagues,

Diesel engines are attractive thanks to their good performance in terms of fuel consumption, drivability, power output and efficiency. Nevertheless, in the last few years, increasing restrictions have been imposed to particulate emissions, concerning both mass (PM) and number (PN).

Different technologies have been proposed to meet emissions standards, and the wall-flow Diesel particulate filter (DPF) is currently the most common after-treatment system used to trap PM from exhaust gases. This technology exhibits good features such that it can be regenerated to remove any accumulation of PM. However, this process involves oxidation of the filtered PM at a high temperature through after- and post-fuel injection strategies, which results in an increase of fuel consumption and may lead to physical damages of the filter in the long-term.

This Special Issue is focused on “New Catalysts and Catalytic Technologies for Diesel Soot Emission Reduction”, with the aim to present the most recent and innovative scientific results in this field. In particular, research papers related to the formulation of specific catalysts to be used in the development of catalytic DPFs, as well as innovative regeneration technologies, are welcome to this Special Issue.

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. 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.
