CO₂ Capture and Conversion Processes: Recent Trends and Future Perspectives

Dear Colleagues,

The amplification of energy demands due to global population growth and modern lifestyles result in increasing CO₂ atmospheric levels, mostly attributed to intensifying fossil fuel industrial production. International initiatives, such as the Kyoto protocol and the Paris agreement, target the significant reduction of CO₂ emissions in order to mitigate climate change. Towards this direction, various technologies have emerged, aiming to capture CO₂ and transform it to useful products. Energy-efficient CO₂ adsorption and absorption processes for capturing CO₂ from various point emission sources and directly from air (DAC), employing innovative low-cost material solvents and membranes, as well as innovative conversion processes including electrocatalytic CO₂ reduction reactions (CO₂RRs) to useful products, are of major importance.

The present Special Issue seeks high quality works, focusing on CO₂ capture and CO₂ conversion technologies. The aim of the Issue is to collect recent research and review works related to the aforementioned processes targeting CO₂ mitigation.

Topics include, but are not limited to, the following:

CO₂ capture technologies:

• Direct air capture (DAC)
• Direct ocean capture (DOC)
• Post-combustion capture
• Pre-combustion capture
• Oxy-fuel combustion
• Chemical looping combustion
• Cryogenic separation

CO₂ capture methods:

• Absorption
• Adsorption
• Membrane separation
• Hybrid processes

CO₂ conversion technologies:

• Catalytic processes
• Dry reforming of methane (DRM) to sygas production
• CO₂ hydrogenation to high-value products
• Electrocatalytic CO₂ reduction reaction (CO₂RR)
• Microbial electrosynthesis systems (MESs)
• Photocatalytic CO₂ reduction

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. Processes is an international peer-reviewed open access semimonthly 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 2400 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.
