Critical Review on Carbon-Based Nanomaterial for Carbon Capture: Technical Challenges, Opportunities, and Future Perspectives

Abstract

In the 21st century, climate change and global warming are considered to be one of the world’s most severe and biggest environmental threats to humans. Consequently, the CO2 capture and storage technique has been a concern as a superior technique by both industrial and academic research communities, which prohibits the mixing of CO2 from point sources, such as cement plants and fossil fuel power plants, into the atmosphere. Particularly, after the United Nations Climate Change Conference in 2015, which was held in Paris, France, researchers have been vigorously focusing on the reduction of greenhouse gases. Presently, liquid amine scrubbing has been used for CO2 capture technology, while solid sorbents are used for CO2 capture technology to overcome the drawbacks associated with amine scrubbing technology. In this review, different carbon nanomaterials, such as fullerene, carbon nanotubes, graphene oxide, biochar, and activated carbon, and their derivatives for CO2 capture applications are summarized. In addition, the review covers the fundamental requirements of solid sorbents, advantages and disadvantages of other solid sorbents, and policies proposed for reducing greenhouse gas emissions by developing and developed countries, which will be highly beneficial for making future policies and fabricating low-cost CO2 sorbents. Finally, the current technical challenges and opportunities for the development of efficient and practically possible carbon-based CO2 sorbents were discussed. Furthermore, future perspectives were proposed for the development of carbonaceous porous materials in place of existing liquid amine scrubbing technology in the future.

Freestanding and Consecutive Intermixed N-Doped Hard Carbon@Soft Carbon Fiber Architectures as Ultrastable Anodes for High-Performance Li-Ion Batteries

“…These results highlight the significant impact of the appropriate carbonization temperature on the rate performance of carbon fibers. Compared with previously reported self-supporting carbon materials, as shown in Figure c, CCNF-800 also showed excellent reversible ability, such as preasphaltene-based carbon nanofibers, carbon fiber-reduced graphene oxide, polyimide-based carbon nanofiber membranes, carbon nanofibers obtained by carbonizing polypyrrole and PAN, and lignin-derived carbon nanofibers.…”

A Review on the Recent Scientific and Commercial Progress on the Direct Air Capture Technology to Manage Atmospheric CO2 Concentrations and Future Perspectives

“…However, amine is carcinogenic in nature and can be oxidized with air content in the feed gas and also does not effectively operate when CO 2 concentrations are low. The functionalized nanoparticles, plasma-modified N/O-doped porous carbon, and carbon nanomaterials are further able to improve the efficacy of amine absorbents. − …”

Thermally activated bipyridyl-based Mn-MOFs with Lewis acid–base bifunctional sites for highly efficient catalytic cycloaddition of CO2 with epoxides and Knoevenagel condensation reactions

“…[1][2][3] To solve these problems, various technologies such as carbon dioxide capture and sequestration (CCS) are being pursued. [4][5][6][7] However, one of the most ideal methods to reduce the amount of CO 2 in air is to recycle CO 2 for industrial applications. [8][9][10] In fact, CO 2 molecules as the C1 feedstock have been intensively developed and converted into value-added chemicals such as dimethyl carbonates, formic acid and cyclic carbonates.…”
