Metal–Organic Frameworks with Incorporated Carbon Nanotubes: Improving Carbon Dioxide and Methane Storage Capacities by Lithium Doping

Abstract

Permanent storage: The gas storage capacities of metal–organic frameworks can be increased by incorporation of carbon nanotubes and doping of the resulting framework with lithium ions (see picture, C turquoise, Cu green polyhedra, Li purple, O red). This combination of modifications results in an improvement of the CO2 and CH4 uptakes by about 305 % and 200 % (T=298 K and P=18 bar), respectively, compared to the unmodified compounds.
