Progress in CO₂ Storage Materials

Dear Colleagues,

This Special Issue comprehensively examines cutting-edge advancements in materials science for CO₂ capture, fixation, and storage, addressing the urgent need for efficient carbon sequestration solutions. The collection highlights breakthrough developments across three key material categories: high-performance sorbents including metal-organic frameworks (MOFs), amine-impregnated porous materials, and advanced solid adsorbents; innovative fixation materials such as mineral carbonates and biochar-based composites; and novel storage media featuring engineered porous polymers and hybrid matrix systems. Particular emphasis is placed on the molecular design of materials with tailored pore architectures and surface chemistries to enhance CO₂ uptake capacity, selectivity, and cycling stability under realistic operating conditions. The issue also explores integrated approaches that combine capture with storage or utilization, including direct mineralization techniques and catalytic conversion pathways. By presenting both fundamental studies and applied research, this special issue provides a holistic perspective on the development of next-generation CO₂ management materials that balance performance metrics with scalability, cost-effectiveness, and environmental sustainability, ultimately contributing to global decarbonization efforts across energy and industrial sectors.

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. Molecules 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 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.
