Dear Colleagues,

A great challenge in the field of catalysis is the synthesis of catalysts with enhanced catalytic activity, selectivity, and durability. The structural and compositional complexity of the catalytic system requires a strong systematic approach to elucidate the nature of the catalyst’s active sites. A catalytic active site is a mono- or polyatomic entity with a specific electronic surface configuration, able to generate a catalytic act (adsorption, dissociation of reactant molecules, and desorption of reaction products).

In-depth knowledge of the composition, structure, and nature of active sites provides the possibility of tailoring the catalytic properties in order to improve catalytic performance (activity and selectivity). Such properties that can be targeted by synthesis are controlled porosity, sintering, resistance, large specific surface area, optimal acid–base properties, lattice vacancies, metal–support interaction, catalyst design, conductivity, etc.

Therefore, the change in catalyst properties leads to modified kinetic parameters (reaction rate, activation energy) and the reaction mechanism.

Improving catalytic performance by modifying catalysts should play an important role in the current global situation by reducing the negative impact on the environment and supporting the sustainable use of natural resources.

The purpose of this issue is to present state-of-the-art strategies for modifying catalysts, aiming to provide an important contribution to the development of research in this area from both practical and theoretical perspectives.

We aim to gain a better understanding of catalytic systems, facilitating the establishment of correlations between composition and physical–chemical properties and performance.

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.
