Research on Heterogeneous Catalysis—2nd Edition

Dear Colleagues,

Heterogeneous catalysis encompasses a broad range of catalyzing solids and highly relevant industrial processes for the production of materials, fine chemicals, and fuels. Subjects of academic and industrial research in this field span from the atomic to the macroscopic scale, from fast bond-making/breaking processes to slow catalyst deactivation timescales. The majority of catalytic studies break down to one central theme of surface science that ultimately determines the performance of a catalyzing material—that is, catalytic active sites and their chemical nature, number, distribution, and accessibility. Nevertheless, catalyzing solids possess a 3D structure that is rarely uniform and often imposes difficulties in determining catalytic active sites and their change concerning underlying catalytic mechanisms. The complexity of catalyst particles can range from well-defined supported metal nanoparticles to millimeter-sized, multicomponent catalyst bodies with a multitude of often very distinct functionalities. Importantly, the relationship between surface structure, composition, and catalytic properties needs to be established under operating conditions. Reaction conditions in catalytic reactors vary from the gas to the liquid phase, and from low to high pressures as well as temperatures. As such, to completely understand the heterogeneous and dynamic nature of a catalyzing solid, informative single-point spectroscopic measurements should be conducted using microscopic methods. The complex multidisciplinary scope of heterogeneous catalysis requires a plethora of characterization approaches that are capable of studying various aspects of surface science.

While the research on heterogeneous catalysis is full of challenges, advances have been made in this field. This Special Issue is devoted to new developments of heterogeneous catalysis with a broad scope. We expect to collect original research articles about this topic, with the aid of Molecules as an excellent platform.

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. Molecules is an international peer-reviewed open access semimonthly 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.
