Special Issue Information

Dear Colleagues,

In recent years, with the aggravation of environmental pollution and energy shortages, the use of catalytic technology to solve the related problems has attracted more and more attention. For example, with the help of metal or metal oxide catalysts, CO2 reduction is carried out in the way of photocatalysis, thermocatalysis or electrocatalysis to achieve the goal of carbon neutrality, and the splitting of water to produce hydrogen is carried out in the way of electrocatalysis or photocatalysis to promote the development of hydrogen economy. However, at present, the catalytic mechanism still needs to be further explored and revealed, the catalytic activity of the materials needs to be further improved and optimized, and the development and application of new catalytic materials need a lot of exploration work. In this Special Issue, we welcome articles focused on the applications and properties of metals and metal oxides in 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. Metals 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 2600 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.

Mn-Ce catalysts modified by Mo were loaded on low-density porous ceramics (LDPC) for simultaneous denitrification and dust removal. The Mn-Ce-Mo catalyst on LDPC had nearly 99% NOx conversion efficiency from 120 °C to 200 °C and still maintained more than 90% NO [...] Read more.
Mn-Ce catalysts modified by Mo were loaded on low-density porous ceramics (LDPC) for simultaneous denitrification and dust removal. The Mn-Ce-Mo catalyst on LDPC had nearly 99% NOx conversion efficiency from 120 °C to 200 °C and still maintained more than 90% NOx conversion efficiency when the filtration velocity reached to 4 m/min. Mn-Ce-Mo catalysts/LDPC not only exhibited excellent catalytic performance at low temperature, they also exhibited good resistance to H2O and SO2. The NOx conversion efficiency remained above 89% at 160 °C when the flue gas contained 100 ppm SO2 and 7 vol.% H2O. The analysis of NH3-TPD and XPS confirmed that Mn2Ce1Ox catalysts modified with Mo had the stronger surface acidity and more adsorbed oxygen, leading to higher NH3-SCR activity and better resistance to SO2 and H2O.
