Recent Advances in Carbon Dioxide Capture, Conversion and Utilization

Dear Colleagues,

Carbon dioxide (CO₂) capture, conversion, and utilization (CCU) technologies have gained increasing attention in recent years due to the urgent need to mitigate greenhouse gas emissions and the potential of converting CO₂ into a valuable resource. Recent advances in CCU include:

1. Carbon capture technologies: Carbon capture technologies aim to capture CO₂ from power plants and industrial processes before it is released into the atmosphere. Recent advances in carbon capture include the development of novel materials such as metal–organic frameworks and amine-functionalized sorbents that can selectively capture CO₂. Membrane-based technologies, such as gas separation membranes, have also been developed to separate CO₂ from other gases.
2. Carbon dioxide conversion: CO₂ conversion technologies aim to convert captured CO₂ into useful products such as chemicals, fuels, and building materials. Recent advances in CO₂ conversion include the development of thermochemical, electrochemical, and photocatalytic processes for converting CO₂ into value-added chemicals, such as methanol, formic acid, and various types of hydrocarbons. Biological processes such as photosynthesis and microbial fermentation have also been explored as potential CO₂ conversion technologies.
3. Carbon dioxide utilization: CO₂ utilization technologies aim to use captured CO₂ as a feedstock for the production of value-added products. Recent advances in CO₂ utilization include the use of CO₂ in the production of concrete, where CO₂ is used to cure concrete and reduce its carbon footprint. CO₂ can also be employed in the production of chemicals such as urea, which is used as a fertilizer.

Overall, recent advances in CCU technologies have the potential to significantly reduce greenhouse gas emissions while creating new economic opportunities. However, more research and development are needed to scale up these technologies and make them commercially viable.

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.
