(225n) Synthesis of Heteroatom-Doped Activated Carbon Using Acrylamide for CO2 Adsorption

Continuous release and the consequent increase in the concentration of greenhouse gases (GHGs) into the atmosphere are causing environmental issues such as climate change and ecosystem destruction. Among these GHGs, carbon dioxide (CO₂) is highly impactful due to its high global warming potential (GWP), which is caused by its accumulation in large amounts over long periods. To mitigate this, various technologies have been developed to reduce the amount of CO₂ released into the atmosphere. Carbon capture and storage (CCS) technology is considered a practical strategy for existing industrial facilities. However, the CO₂ capture process is the most expensive step in CCS, so effective CO₂ capture methods are essential. Among these CO₂ capture methods, adsorption using activated carbon (AC) is gaining attention due to its cost-effectiveness in material manufacturing, operating conditions, and regeneration. Ongoing research is required to develop activated carbon to ensure effective industrial CO₂ capture. In this study, heteroatom-doped activated carbons were synthesized from acrylamide as the precursor. We investigated the impact of different variables in material preparation on the textural properties and CO₂ uptake of heteroatom-doped activated carbon.
