Abstract
The transition from fossil fuels to more sustainable energy sources is expected to take several decades. A major challenge in the interim is efficient capture, purification, and upgrading of carbon dioxide (CO2). The development of novel heterogeneous catalytic systems is essential to address many of the technological and economic challenges at hand. Nanostructures based on non-noble metals have been traditionally understudied due to their high chemical instability in both synthesis and application. The unique sensitivity and chemical reactivity of their nanostructures, however, offer the possibility for designing new catalytic systems with inherent benefits (e.g., product selectivity, mass activity, and cost). This thesis contains two parts: first on the development of nanomaterial systems for the purification of CO2 from flue gas by the catalytic reduction of oxygen (O2) and second on the design of novel catalysts for the thermal and electrochemical reduction of CO2. This research aims at combining the fundamentals of nanostructures and catalysis with practical applications such to provide new processes for the sequestration and utilization of CO2.
