Biomass as a source of adsorbents for CO2 capture

Abstract Climate change has become one of the main challenges of 21st century, and the rising level of CO2 is considered as the main source of this problem. Although greenhouse gases such as methane and chlorofluorocarbons have a much greater effect than CO2, the latter is still responsible for 70% of global warming. In this way, carbon capture and storage technology has emerged as a combination of several processes to manage this problem and reduce the CO2 emissions. In this way, several adsorbents have been considered for CO2 capture, while every one of these sorbents has different benefits and some drawbacks; carbon-based materials, due to their hydrophobicity character and easy to handle, are among the most popular ones. On the other hand, biomass-derived activated carbons owing to their low-cost of synthesis, high uptake capacity, hydrophobicity character, and abundant resources have attracted much attention, in recent years.
