Special Issue Information

Dear Colleagues,

Heterogeneous catalysis has played a crucial role in the development of modern society by facilitating commodities produced from petrochemicals, the upgrading of petroleum for fuel and energy applications, and the production of fertilizers to feed the growing population. In the future, catalysis will play an increasing role in the shift to utilizing renewable energy effectively to make chemicals.

The need to minimize the environmental impacts of producing our chemical commodities is becoming increasingly urgent. There is a great opportunity for heterogeneous catalysis to accelerate the shift towards a circular economy where our chemicals will be produced from sustainable feedstocks, with lower energy demands and with more focus on producing materials that can be easily recycled back into the chemical supply chain.

We invite submissions on a wide range of subjects concerning sustainable chemical transformations, including but not limited to selective oxidation/hydrogenation, novel catalyst preparations, conversions of renewable feedstock, catalysts for clean energy conversion into chemicals and polymer degradation into useful starting materials.

All these research areas will help drive progress in the transition towards a society where we can produce the materials we need in a sustainable manner as we transition towards a chemical industry with greater integration between raw material and final products.

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. 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.

This study presents the synthesis, characteristics and catalytic reactivity of sustainable bifunctional heterogeneous catalysts derived from coal fly ash-based geopolymer, particularly those with a high Ca content (C-class) fly ash. The developed catalysts were synthesized at room temperature and pressure in a simple ecologically-benign procedure and their reactivity was evaluated in the Friedel-Crafts acylation of various arenes. These catalysts can be produced with multilevel porous architecture, and a combination of acidic and redox active sites allowing their use as bifunctional catalysts. The acidic sites (Lewis and Brønsted acidic sites) were generated within the catalyst framework by ion-exchange followed by thermal treatment, and redox sites that originated from the catalytically reactive fly ash components. The developed catalysts demonstrated higher reactivity than other commonly used solid catalysts such as Metal-zeolite and Metal-mesoporous silicate, heteropolyacids and zeolite imidazole frameworks (ZIF).
