Knowledge of the structure and composition of active sites is crucial to understand heterogeneous catalysts and design more efficient ones. This is particularly true since the scarcity of some elements such as noble elements widely used in energy and environment fields will require doing better with less. As suggested by Taylor in 1925, active sites are considered as atoms or ensembles of atoms sparse on the surface which directly catalyze a reaction. Active sites change in a dynamic way during adsorption of reactants or reaction intermediates, and this dynamic restructuring plays an important role in bond activation. Detailed description of active sites using advanced in situ/operando techniques with high temporal and spatial resolutions as well as DFT modeling allow establishing structure–activity relationships. They are particularly interesting for single atoms and subnanometric clusters, which can be distinguished by the atomically resolved microscopes. The investigation of their catalytic properties compared to nanosized particles is crucial to determine if their presence has to be favored or avoided. Furthermore, the interface between such sites and support also deserves investigation, considering their limited size (few atoms) and since they play a key role in their structural and electronic properties, leading to important support effects. Stability and regeneration of active sites are also important topics since, for instance, they can be poisoned with relatively few molecules present in a complex feed. Finally, the design of multifunctional catalysts has led the catalysis community to investigate the role of nanoscale intimacy as well as other effects at atomic and long-range scales.
In this context, I am inviting you to submit your recent achievements to this Special Issue on “Active Sites in Heterogeneous Catalysis” in the form of original research articles or short reviews. Heterogeneous catalysis includes photo- and electrocatalysis and covers all application fields.

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 papers will be 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 1600 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.
