Recent Advances in Nanostructured Catalysts

Dear Colleagues,

Catalysts represent one of the pillars of green chemistry and are needed for a large variety of applications, including the synthesis of chemicals and drugs as well as for biosensoristic and organic transformations. Catalyzed reactions require a lower activation energy for the synthesis of chemicals, and higher efficiency has been observed due to the generation of fewer undesired compounds and other waste substances. Catalysts can be designed to be environmentally safe, and different types of solid catalysts are currently being applied in the research and chemical industries. The main advantages of heterogeneous catalysts in terms of the green synthesis of chemicals are their recovery and recycling to perform reactions at each step instead of using additional reagents such as those used in the initial process. In addition, solid materials represent one the most versatile components of heterogeneous catalysis, and further study can greatly enhance understanding of the specific active sites, reaction mechanisms, reaction pathways, and the selectivity toward desirable chemicals; solid catalysts also play a significant role in the development of environmentally ecofriendly processes. Among the various heterogeneous catalysts, nanostructured supports present several advantages such as in stability, reusability, large specific surface area, reduced mass transfer limitation, ease of modification, unique geometry, and size/shape-dependent characteristics. The incorporation of catalysts and biocatalysts into nanostructured materials is particularly noteworthy from a structural perspective since there are opportunities in those systems to establish a long-term life cycle for the active species and suitable microenvironments in the case of enzymes. This Special Issue is focused on the more recent preparations of nanostructured catalysts and their different applications, from medicinal chemistry to sensoristic, proteomics, and organic transformations.

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-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 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.
