Sol–Gel Chemistry: A Toolbox for Catalyst Preparation

Dear Colleagues,

Sol–gel chemistry encompasses a wide range of chemical routes that allow producing tailored solid materials starting form molecular precursors. Specifically in the field of heterogeneous catalysts preparation, sol–gel methods permit the design of advanced catalytic formulations showing unique properties. Taking advantage of the controlled synthesis conditions in sol–gel methods, chemists develop catalytic materials which exhibit improved catalytic performance thanks to their advantageous textures, structures, compositions, homogeneity, surface functionality, etc. This field is evolving quickly as, for example, new processing modes, new molecular precursors or new templating agents are proposed.

In fact, our ability to modernise industrial chemistry, strongly relies on our aptitude to design and understand new types of catalysts with specific properties and exhibiting remarkable catalytic behaviour. The challenges are numerous. The transition from a petro-based chemical industry to a bio-based one requires multifunctional catalysts that can withstand polar working conditions. Embracing the huge potential of natural or genetically engineered enzymes requires effective immobilization strategies to obtain efficient heterogeneous biocatalysts. Turning batch chemical processes into continuous flow mode processes requires catalysts that can be moulded so as to allow optimal mass transfer. In all these examples, sol–gel chemistry can help shape innovative solutions.

This Special Issue aims to cover recent progress and trends in synthesizing advanced heterogeneous catalysts by sol–gel chemistry routes.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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 2200 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.
