A comprehensive review of the physicochemical properties and performance of novel carbon-based adsorbents for CO2 capture.

Given the pressing challenges associated with CO₂ emissions and the ongoing efforts to mitigate greenhouse gas concentrations, the development of effective CO₂ control strategies has become increasingly critical. Among the various approaches, CO₂ adsorption emerges as a promising method for reducing greenhouse gases. With the extensive availability of carbon on Earth, the use of carbon-based materials (CBMs) not only offers an efficient solution but is also economically viable, capitalizing on the unique properties inherent in carbonaceous materials. CBMs encompass a diverse array of structural forms, including activated carbon (AC), graphene, graphite, carbon nanotubes (CNTs), carbon nanofibers (CNFs), biochar, hydrochar, and carbon aerogels (CAs). Each of these materials presents distinct advantages for CO₂ capture, attributed to their variable surface functionalities and structural characteristics. Exploring novel adsorbents with tunable surface properties, enhanced porosity, and innovative morphologies represents an intriguing and imperative direction for future research. By focusing on designing and optimizing these advanced materials, technologies for CO₂ capture can be performed significantly more effectively and efficiently, which can assist in focusing on climate change more sustainably.
