This dissertation presents research on the chemistry of carbon dioxide capture and mineralization which has been accomplished with a variety of solid-state nuclear magnetic resonance (NMR) spectroscopy techniques. Materials used for carbon capture interact with CO2 through different adsorption mechanisms, physisorption and chemisorption. The physisorption systems studied have shown that adsorbed CO2 undergoes a hopping mechanism within the material. The studies of chemisorption systems indicate a mixture of adsorption products forms during the adsorption interaction. Carbon mineralization reactions have been studied to better understand the reactions that can occur at underground carbon sequestrations sites that are used for storing CO2. Here it has been shown that NaCl affects the chemistry in these reacting systems, which can be seen with NMR. The limitations of the ability of NMR to study carbon mineralization reactions have also been investigated. This research shows that solid-state NMR is a useful tool for studying carbon capture and mineralization as well as describing the interactions of CO2 in these systems.
