Over the past several years, cerium oxide (CeO2) has received a great deal of attention as a support in heterogeneous catalysis due to the remarkably active Ce4+/Ce3+ redox pair and the efficient oxygen vacancies responsible for its high oxygen storage capacity (OSC). Apart from the intrinsic properties of ceria, structural characteristics such as the size and shape of ceria have been found to play a crucial role in the catalytic performance of Ce-based catalysts. In addition, the doping of ceria support with other elements of different ionic radii or the formation of a solid solution with another metal oxide can also greatly increase the reducibility and the oxygen exchange capacity. Furthermore, it is generally accepted that high dispersion or even atomic dispersion of active metals on the surface of ceria needs to be achieved in order to enhance the strong metal support interaction and thus the performance of Ce-based catalysts. The use of appropriate characterization techniques (e.g., HR-TEM, high-pressure-XPS, EPR), in situ spectroscopic experiments, and intrinsic kinetic data acquired from theoretical calculations and catalytic experiments need to be combined in order to investigate the correlation between structure and catalytic performance.
This Special Issue aims to cover recent progress and advances in Ce-based catalysts:
- In redox reactions (e.g., CO oxidation, WGS, soot combustion and VOCs oxidation);
- In reforming processes (e.g., alcohol reforming for H2 production);
- In photocatalysis (e.g., for wastewater treatment and water splitting);
- In thermochemical water splitting (e.g., for solar reactors for the thermal splitting of H2O and CO2 for fuel generation);
- In fuel cells (e.g., SOFCs or PEM FCs)
This includes novel synthesis methods of catalysts, in situ characterization techniques, and kinetics results over the above-mentioned applications.Dr. Joan Papavasiliou
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.
