Activated Carbon from Palm Date Seeds for CO<sub>2</sub> Capture

The process of carbon dioxide capture and storage is seen as a critical strategy to mitigate the so-called greenhouse effect and the planetary climate changes associated with it. In this study, we investigated the CO<sub>2</sub> adsorption capacity of various microporous carbon materials...
