Enhancing Direct Air Capture through Potassium Carbonate Doping of Activated Carbons

N. van Dongen, A. J. F. van Hoof, S. Calero, J. M. Vicent-Luna. Direct air capture of carbon dioxide (CO$_2$) is one of the most promising strategies to mitigate rising atmospheric CO$_2$ levels. Among various techniques, adsorption using porous materials is a viable method for extracting CO$_2$ from air, even under humid conditions. However, identifying optimal adsorbent materials remains a significant challenge. Moreover, the performance of existing materials can be improved by doping with active species that boost gas capture, a relatively unexplored fiel
