Dear Colleagues,

Solar-driven CO₂ reduction into high-value fuels has emerged as a hot-spot research topic in an attempt to deal with the environmental crisis over the past few decades. Hitherto, various pathways have been developed to promote CO₂ reduction. However, the performance of current catalysts has still been low due to the utilized material and reactor. Utilization of sustainable hydrogen has turned out to be a promising approach to boost CO₂ reduction in terms of solar conversion efficiency and selectivity. Thus, the generation of high-value chemicals produced in CO₂ reduction reaction is feasible with the assistance of hydrogen. Therefore, this approach offers great opportunities for the generation of high-value chemicals from CO₂. In this context, the exploration of robust materials and proper catalytic reactors has been considered the key component to address those aforementioned restrictions.

This Special Issue aims at providing novel approaches toward photocatalytic CO₂ reduction associated with sustainable hydrogen. This issue will cover state-of-the-art development of material-, reactor-, and theoretical-related investigations in the field the solar-driven hydrogenation of CO₂.

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 2700 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.
