Dear Colleagues,

As an important catalyst in heterogeneous catalysis, nanomaterials are widely used in fine chemical synthesis, environmental remediation, renewable energy development, efficient biotransformation, and other areas of interest. Recently, as well as their use in thermally catalytic reactions, nanoscale catalysts play an increasingly significant role in other kinds of catalysis, such as electro-, photo-, and enzyme-mimicking catalysis. In addition to the benefits of the ease of catalyst separation and recovery, nanocatalysts allow for rapid chemical transformations because of their high surface area and specific surface energy. Moreover, nanocatalysts enable improvements in the reaction selectivity, which is a critical goal when improving conversion efficiency in catalysis, by triggering the reaction with light or other stimulations, reducing the occurrence of side reactions, altering the reaction pathway, etc. Thus, designing new, efficient nanocatalysts and exploring emerging nanocatalysis applications are still of significant interest. Consistently, spectroscopic, microscopic, and other emerging tools used in advanced measurements of nanocatalysts and nanocatalytic reactions are key to understanding the mechanism of nanocatalysis at the atomic and molecular levels, but this remains challenging.

This Special Issue is dedicated to original, novel, and high-impact contributions looking at recent advances in the use of emerging nanocatalysts for a wide variety of applications, as well as experimental and computational studies on the characterization and measurement of nanomaterial-based catalysts and catalytic reactions. Contributions related to photocatalysts, electrocatalysts, nanozymes, organic chemical transformation, CO₂ conversion, N₂ fixation, and energy conversion are also welcome in this issue. Rapid communications, original research articles, and review articles are all accepted.

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.
