Special Issue Information

Dear Colleagues,

When a researcher embarks on chemical processes for the production of fine chemicals, the main goal to pursue is the development of hazard-free, waste-free, and energy-efficient synthetic routes. This “minimalist” approach has become particularly urgent during the 21th century, in consideration of the essential need to protect human health as well as our environment. 

Solid catalysts, such as zeolites, can represent a good alternative to establish cleaner and less polluting processes because of their remarkable properties. They offer shape selectivity as the dimensional constraints of their channels or pores discriminate between molecules with different sizes for both the reactant (transition state) and the product. In addition, they are easily recovered and can be reused with the great advantage of making the chemical process simpler and more economical, reducing the production of waste and/or by-products.

The employment of solid catalysts characterized by tailored active sites, such as zeolites and/or other kinds of solid material that can successfully replace the conventional liquid catalyst, has to be considered as a challenge and an opportunity to promote the catalysis of sustainable chemical processes.

This Special Issue gathers topics concerning the development of chemical reactions catalyzed to be more eco-friendly processes. At the same time, it will also emphasize standard reactions for producing fine chemicals and promoted by solid catalysts, which result in more environmentally acceptable processes, avoiding harsh conditions and the potential undesired degradation of organic molecules to toxic products. 

Kind regards

Dr. Stefania De Luca
Guest Editor

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. Foundations is an international peer-reviewed open access quarterly 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 1000 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.

Zeolites, both natural and synthetic, are certainly some of the most versatile minerals for their applications. Since the 1940s, they have been used in the chemical industry as catalysts, adsorbents and ion exchanger extensively, and the development of their practical usage is expected to continue upon years. Their versatility is the result of the combination of peculiar and indispensable properties, each of which can be found in other material as a single property, but seldom all of them are found in combination. However, despite the success of their employment, the mechanisms of many important catalytic processes involving zeolites remained elusive. In particular, the comprehension of the structure–property relationships for emerging applications are highly required. In this perspective article we focus on the role of zeolites as solid acid-base catalysts. We go deeply into the structural properties of the LTA kind (Zeolite-Na A 4 Ångstrom) that was successfully employed as basic catalyst for several nucleophilic substitution reactions. Full article
