Innovation in Adsorption Processes and Materials for CO₂ Capture

Dear Colleagues,

This is a call for papers for a Special Issue on “Innovation in Adsorption Processes and Materials for CO₂ Capture”. One of the most promising alternatives to reduce the increasing amount of CO₂ released into the atmosphere and its negative impact on global climate change is represented by CO₂ capture and storage (CCS), consisting in the separation of CO₂ from large industrial and energy-related sources, transport to a storage location, and long-term isolation from the atmosphere. The main explanation for the slow deployment of fully integrated commercial CCS schemes is the considerable cost of the capture phase, which approximately represents two thirds of the total cost of the whole process. In this framework, adsorption using solid sorbents has been recognized to have the potential to reduce the cost of the capture process compared to amine scrubbing, due to its low regeneration energy consumption, selectivity, easiness in handling, and applicability over a relatively wide range of operating temperatures.

In this context, the choice of the adsorbent material represents a critical point for the success of this approach. Indeed, the sorbent should combine low cost with versatility and good performances, such as high adsorption capacity, fast adsorption/desorption rates, and good stability to repeated adsorption/desorption cycles. Likewise, the selection and set up of a proper adsorption/regeneration process (temperature swing adsorption, pressure swing adsorption, etc.) is also crucial to fully exploit the potential of the selected sorbent.

Therefore, the development of innovative adsorption materials and processes for CO₂ capture are essential in this perspective. The topics that would be covered in this Special Issue include but are not limited to the synthesis, characterization, and application of novel and advanced solid sorbent materials and systems for CO₂ capture by adsorption. Articles focusing on the environmental aspects related to CO₂ adsorption or life cycle analysis will also be 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 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. Materials 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 2600 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.
