【 摘 要 】

An increase in fundamental understanding of ordered and non-ordered derivatives from carbide precursors was proposed. For disordered carbide-derived carbons (CDCs), residual metal sites, textural, and chemical properties were explored and discussed. It was determined that multiple carbide systems can be implemented for the retention of parental metal-based nanoparticles for adsorption processes and catalytic reactions. Changes in the annealing environments of fully etched CDCs were systematically studied elucidating correlations regarding changes in textural, chemical and adsorption properties. It was determined that CDCs can be highly tuned for a myriad of acid gas adsorption applications. Furthermore, for the first time, ordered metal-organic frameworks (MOFs) were derived from a carbide precursor. The use of such an insoluble precursor as both a metal source and templating agent afforded unique morphologies, adsorption properties, and revealed a series of new routes towards synthesizing unique frameworks that are currently difficult or impossible to make through traditional solvothermal reactions. The findings of this dissertation provide a platform for further understanding and development of both carbide-derived carbons and metal-organic frameworks.
