Hierarchical Mesoporous SSZ-13 Chabazite Zeolites for Carbon Dioxide Capture

Artificial carbon dioxide capture is an alternative method to remove the carbon dioxide already accumulated in the atmosphere as well as to stop its release at its large-scale emission points at the source, such as at power plants. However, new adsorbents are needed to make the approach feasible. Fo...
