Special Issue Information

Dear Colleagues,

We are excited to announce a call for papers for a Special Issue focusing on “Carbon Capture, Separation and Utilization”.

The emission of CO2 is intricately linked to human activities across various sectors, including energy, agriculture, industry, and waste management. Alarmingly, energy-related only CO2 emissions has reached an all-time high of over 36.8 Gt in the past 2022. This surge in emissions has raised global concerns about greenhouse effects and environmental issues. Consequently, reducing CO2 emissions has become a crucial objective in many leading countries, which possesses challenges and also opportunities for developing advanced technologies for carbon capture, separation, and utilization.

Addressing the issue of CO2 emission requires a diverse range of technologies because the emission of CO2 varies in terms of locations, modes, volumes, and sources across the planet. Substantial research efforts have been devoted to reducing CO2 emissions from fossil fuel combustion, as it accounts for approximately 40% of total emissions. Available technologies include reducing CO2 formation prior to fuel combustion and also capturing CO2 from flue gas streams. Recent advancements have also been made in areas such as direct CO2 capture from ambient air, downstream utilization of CO2 for enhanced oil/brine recovery, and CO2-to-fuel conversions.

Therefore, we invite researchers to contribute their latest research and insights to this Special Issue. We welcome papers that encompass a wide range of topics related to CO2 capture, separation, and utilization. The preferred paper scope includes, but is not limited to, pre- and post-combustion carbon capture technologies, CO2 capture from the ambient environment, CO2 utilization in natural resources extraction, CO2 conversion to value-added products, and novel materials with the potential to mitigate CO2 emissions.

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. Separations is an international peer-reviewed open access monthly 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.

Various porous polymer materials have been prepared for the separation of CO2 from mixed gases. However, complex processes, expensive monomers, and costly catalysts are commonly used for their synthesis, making the adsorbents difficult to achieve in industrial applications. Herein, we developed a strategy to fabricate a series of benzene rings containing porous polymer materials (B-PPMs) via a facile condensation reaction of two inexpensive monomers, namely tetraphenylsilane and 1,4-bis(bromomethyl)benzene. The B-PPMs are verified to have accessible surface areas, large pore volumes, and appreciate pore sizes via a series of characterizations. The B-PPM-2 exhibits the best CO2 adsorption amount of 67 cm3·g−1 at 273 K and 1 bar, while the CO2/N2 selectivity can reach 64.5 and 51.9 at 273 K and 298 K, respectively. Furthermore, the adsorbent B-PPM-2 can be completely regenerated after five cycles of breakthrough experiments under mild conditions, which may provide promising candidates for selective capture of CO2 from mixtures.
