Developing new technologies for carbon sequestra-tion and long-term carbon storage is important. Clay minerals are interesting in this context as they are low-cost, naturally abundant, can adsorb considerable amounts of CO2, and are present in storag

Due to the compact two-dimensional interlayer pore space and the high density of interlayer molecular adsorption sites, clay minerals are competitive adsorption materials for carbon dioxide capture. We demonstrate that with a decreasing interlayer su

Clay minerals can adsorb large amounts of CO2 and are present in anthropogenic storage sites for CO2. Nanoscale functionalization of smectite clay minerals is essential for developing technologies for carbon sequestration based on these materials and

Abstract One can find conductive, semiconducting, and insulating single nanosheets with unique electronic properties that are tied to their two-dimensional (2D) structure. Here, we report on wide-bandgap 2D insulator nanosheets obtained by delaminati
