Special Issue Information

Dear Colleagues,

This Special Issue aims to provide an overview of the recent applications of bimetallic and trimetallic catalysis, highlighting the growing importance in a number of areas including reforming, hydrodesulfurization, dehydrogenation, aromatization, and polymerization reactions. Such catalysts have gained increasingly more traction due to the synergy of active phases, which is expected to significantly enhance the performance of the process compared to single-metal catalysts. Despite a significant number of researchers focusing their attention on the employment of bimetallic/trimetallic formulations, the catalytic mechanisms that result in the above-described performance improvements have not been clearly illustrated yet. There are still several aspects that need to be investigated in depth; the development of methods for synthesizing bimetallic and trimetallic catalysts with precise control over their composition and morphology is essential in ensuring the desired synergy and in maximizing the catalytic performance. Moreover, the study of methods for improving stability and limiting sintering and poisoning is crucial in reducing the deactivation phenomena.

Thus, this Special Issue seeks to shed light on the benefits of combining various metals (even in very low amounts); in many cases, the synergetic effect between the two or three phases can result in a better active species dispersion, leading to a larger active surface area available for the reactant molecules to interact with. Furthermore, when certain metals are combined, they can form alloys or solid solutions at an atomic level. These structures can exhibit unique electronic and geometric properties that enhance their ability to interact with specific reactants and influence reaction pathways. Even though research has advanced in bimetallic catalysts, adding a third metal increases system complexity. In this context, advanced chemical–physical characterization analyses of the multi-metal catalysts, such as high-resolution electron microscopy and X-ray absorption techniques, can provide valuable insights into these innovative materials.

Both experimental and theoretical works, including original research, review articles, and short communications, are consistent with the scope of this SI and are welcome.

Topics include but are not limited to the following fields:

  • Reforming;
  • Water–gas shift;
  • Hydrogenation/dehydrogenation;
  • Aromatization;
  • Polymerization;
  • Hydrodesulfurization;
  • CO2 electroreduction;
  • Alcohol oxidation.

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.
