Feature Papers in Catalytic Materials

Dear Colleagues,

The rapid increase in global carbon dioxide (CO₂) emissions has led to significant concerns regarding climate change and its detrimental effects on the environment. As a result, there is a growing interest in finding innovative solutions to mitigate these emissions and develop sustainable practices. One promising approach is the catalytic valorisation of exhaust carbon, which involves the conversion of CO₂ into valuable chemicals and fuels using catalytic and electrocatalytic processes. Dry reforming of alcohols or hydrocarbons for syngas production, CO₂ methanation, and CO₂ electrochemical reduction are valid approaches to transform CO₂ emissions into valuable products, thereby reducing the environmental impact of carbon emissions and promoting a circular carbon economy. However, some challenges remain, such as the development of efficient and stable catalysts, the understanding of reaction mechanisms, and the integration of these processes into large-scale industrial technologies. In this sense, developing photocatalysts with high photo-conversion efficiency may solve the ensuing energy crisis and environmental concerns.

The choice and design of catalysts and electrode materials are key factors that determine the efficiency, selectivity, and economic viability of the valorisation process. The aim of the present Special Issue is to shed light on the possibilities and challenges of exhaust carbon valorisation and to inspire further technological innovation in this important area of research. Attention will be paid to the design of materials for CO₂ capture and storage; new catalysts for CO₂ conversion via dry reforming reactions for syngas production; Fischer–Tropsch synthesis for syngas valorization; hydrogen purification in terms of water–gas shift reaction (WGS) and preferential CO oxidation (PROX); and CO₂ methanation. Moreover, the present issue will be devoted to new insights into photocatalytic materials (such as Titania/ceria/C3N4) and solid oxide electrolysis cells for CO₂ conversion.

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.
