Ionic Liquids for Carbon Dioxide Capture

Dear Colleagues,

Ionic liquids are interesting compounds, defined as salts with a melting point below 100 °C. Their main properties are related to their ionic nature. Having strong interactions between the different ions, the consequences are a high enthalpy of evaporation, and thus, a low vapour pressure, often combined with high thermal and chemical stability and ionic conductivity.

On the other hand, access to a large library of anions and cations allows us to exploit them to obtain the desired properties. This fact, combined with the possibility of introducing specific functional groups, makes them perfect candidates for carbon dioxide capture and separation.

Many studies have been conducted on the use of ionic liquids for carbon dioxide capture and separation, but many problems remain, e.g., impurities such as water can impair functionality or the usual high viscosity can be a problem for industrial processes. The sometimes erroneous belief that these compounds are expensive compared to others does not mean that the entire IL-capture and purification process should also be expensive.

This Special Issue invites all researchers and industrial developers to publish work in the following fields related to the adsorption, capture and separation of CO₂ from exhaust gases, biogas, other industrial effluents or direct air capture (DAC). Emphasis will be on industrial CO₂ sources and real-life systems. Submissions are welcome for topics including, but not limited to:

1 Development of new task-specific ionic liquids;
2 Application of ionic liquids in industrial/pilot plants;
3 Supported ionic liquids/polymeric ionic liquids as absorbent materials;
4 Supported ionic liquid membranes;
5 New theoretical models of industrial plants using ionic liquids.

Papers on other CO₂-capture-related chemical/physical processes taking place in ionic liquids will also be considered. Submissions containing computational data and experimental data, as well as review articles by experts in the field, are also welcome.

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. Liquids is an international peer-reviewed open access quarterly 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 1000 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.
