Ceria-Based Catalysts, 2nd Edition

Dear Colleagues,

Following the first successful Special Issue on this topic (available here), we are happy to announce a second edition entitled “Ceria-Based Catalysts, 2nd Edition”.

Cerium oxide plays a key role as an active support and as a catalyst in the relevant environmental applications and energy conversion systems. Additionally, its unique ability to shuttle between the Ce(III) and Ce(IV) oxidation states, hence its oxygen storage capacity (OSC), is particularly valuable in photocatalysis, where cerium-based materials can act as oxygen buffers, promoting oxidative activities. Thus, the development of advanced ceria-based catalysts has become a hot topic of ongoing research, including several applications spanning from advanced gas purification to fuel cells. Special attention has been paid to the synthesis of advanced ceria nanostructures (i.e., nanoparticles, 1D, 2D, 3D or core–shell materials) and to the relationship between structure and catalytic activity. In fact, it has been widely stated that the (photo)catalytic activity of cerium oxide is strongly influenced by its size and crystalline structure. Another critical point on the development of ceria-based photocatalysts is the discrepancy between the theoretical and experimental bandgaps of these materials that, due to rapid electron–hole recombination, strongly limits the overall photocatalytic efficiency.

Therefore, this Special Issue aims to highlight recent advances in the synthesis, characterization and catalytic/photocatalytic applications of cerium-containing catalysts, going beyond the state-of-the art. Researchers are encouraged to submit their most recent advances on this topic.

If you would like to submit papers to this Special Issue or have any questions, please contact the in-house editor, Ms. Rita Lin ([email protected]).

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.
