Special Issue Information

Dear Colleagues,

Heterogeneous catalysis is now vital in the chemical industry, considering that over 90% of all chemical manufacturing is based on catalytic processes, and the fact that catalysis contributes to approximately 35% of the world's gross domestic product.

Catalytic reactions do not only occur on the basis of the production of several chemicals and materials, but they play a crucial role in energy applications, pollution control, medical applications, and food production. Progressively, more and more, the increasingly complex reaction networks require not only a given desired conversion being promoted, but any undesirable side reactions must also be avoided: the essential target today deals with an improvement in reaction yields, the simplification of the overall manufacturing process, the elimination of expensive product separation steps, and the minimization of polluting by-products.

Novel nanotechnologies developed in recent years allow for the synthesizing of complex solids with well-defined characteristics. The ability to produce samples with specific sizes or shapes, or to grow complex solid nanostructures, can be exploited to fulfil specific requirements in catalysis in terms of selectivity, as identified via molecular-level investigations on the reaction mechanisms.

This synergy between the surface chemistry of catalysis and nanotechnology is still in its infancy, but has already led to many exciting developments, and promises to revolutionize chemical manufacturing.

For this Special Issue, we welcome work concerning the tenets that can direct research into catalysis, i.e., nanoparticle synthesis, characterization under reaction conditions, and reaction studies using these nanoparticles to determine kinetics, selectivity, deactivation, and other catalytic kinetic parameters which underpin molecular catalysis.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

In the pursuit of designing a reusable catalyst with enhanced catalytic activity, recent studies indicate that electrochemical grafting of diazonium salts is an efficient method of forming heterogeneous catalysts. The aim of this review is to assess the industrial applicability of diazonium-based catalysts with particular emphasis on their mechanical, chemical, and thermal stability. To this end, different approaches to catalyst production via diazonium salt chemistry have been compared, including the immobilization of catalysts by a chemical reaction with a diazonium moiety, the direct use of diazonium salts and nanoparticles as catalysts, the use of diazonium layers to modulate wettability of a carrier, as well as the possibility of transforming the catalyst into the corresponding diazonium salt. After providing descriptions of the most suitable carriers, the most common deactivation routes of catalysts have been discussed. Although diazonium-based catalysts are expected to exhibit good stability owing to the covalent bond created between a catalyst and a post-diazonium layer, this review indicates the paucity of studies that experimentally verify this hypothesis. Therefore, use of diazonium salts appears a promising approach in catalysts formation if more research efforts can focus on assessing their stability and long-term catalytic performance. Full article
