Metal-Support Interactions for Advanced Catalysis

Dear Colleagues,

Supported metal catalysts are an important category of heterogeneous catalysts and are widely applied in various industrial chemical reactions. Metal–support interactions play essential roles in the dispersion of metals with a high surface area and the stabilization of metal particles during catalysis. Such interactions could also have a substantial impact on the shape of the metal particles (e.g., two dimensional versus three dimensional ones), thus tuning catalytic performance remarkably. In the case of noble metals on reducible oxide, they could even cause migration of the oxide to the surface of metal particles after high-temperature reduction, which is called strong metal–support interaction (SMSI). Meanwhile, these interactions might also induce substantial electronic perturbations to metal particles. Such “electronic metal–support interactions” (EMSIs), rationalized in terms of charge transfer, were suggested to modulate the metal d-band centers, thus often leading to outstanding catalytic activity. Therefore, understanding metal–support interactions is essential for tuning the activity, selectivity and stability of oxide-supported metal catalysts.

This Special Issue is focused on, but not limited to, recent progress in characterization, understanding and application of metal–support interactions in heterogeneous catalysis.

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.
