Special Issue Information
Dear Colleagues,
We are excited to invite you to submit your manuscript for publication in our Special Issue on “Emissions Control Catalysis” in Catalysts.
Mobile and stationary engines such as internal combustion engines in transportation and gas turbines in power plants and distributed power generation systems, operate in conditions ranging from stoichiometric to lean to maximize efficiency, minimize fuel consumption, and meet rigorous emissions standards. Depending on the fuel, combustion mode and operating air-to-fuel ratio, engine-out emissions may contain varying levels of harmful regulated pollutants such as carbon monoxide (CO), nitrogen oxides (NOx), unburned fuel or non-methane organic gases (NMOG), which can lead to the formation of acid rain, ground level ozone, and smog. Regulations on these criteria pollutants along with methane (CH4), ammonia (NH3) and particulate matter/number (PM, PN) are getting stricter as the world is moving towards near-zero emissions regulations.
Catalytic emissions abatement technologies are promising for effectively reducing pollutant emissions. However, with increasing regulations, several emissions control challenges arise, some of which are highlighted below:
- Low exhaust temperatures causing the catalyst to cool below its optimum operating temperature range during:
- Cold-start operation;
- High thermal efficiency lean operation;
- Low-load, low-speed operation.
- Ammonia and urea-based Lean NOx control challenges below 200 °C;
- Increasing demands on catalyst performance over its full useful life necessitating resistance to aging effects and high durability;
- Methane slip from natural gas fueled engines used in power generation systems increase green-house gas emissions and methane oxidation under low-temperature lean conditions in the presence of water is particularly challenging;
- Ammonia slip from selective catalytic reduction (SCR) systems for NOx control in stationary power sources.
We invite manuscript submissions on catalytic emissions control technologies which will address these challenges including:
- Three-way catalysts;
- Gasoline particulate filters;
- Diesel particulate filters;
- Hydrocarbon traps;
- Passive NOx adsorbers;
- Ammonia slip catalysts;
- Selective catalytic reduction of NOx;
- Low temperature methane oxidation catalysts.

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 2700 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.
