- 요약The current global energy landscape is at a critical crossroads defined by an urgent need to transition from environmentally detrimental fossil fuel resources. An attractive alternative is to engineer a closed carbon cycle through the conversion of carbon dioxide into energy-dense fuels. Electrochemical reduction of aqueous CO2 can offer a sustainable approach to achieve these transformation reactions; however, the practical implementation of electrocatalysts is challenged by low efficiency and poor selectivity in product generation. Overcoming these obstacles requires strategic considerations in the structural and functional design of materials. One such focus has centered around porous materials that can enhance the efficiency of C-C bond generation through modification of the local electrochemical environment via confinement effects.This work further explores the synthesis and electrochemical applications of porous materials. Chapter 2 of this dissertation introduces a chromium-gallium oxide mixture that, when in the presence of trace metal, can achieve unprecedented efficiency in the generation of multi-carbon products from CO2. This includes four-carbon products that possess energy densities comparable to conventional fuels. It is concluded that the observed reactivity is enabled by the intrinsic porosity of the metal oxide mixture, which can increase the local concentration of CO2 at the electrode interface and thereby enhance proton/electron transfer rates. Chapter 3 continues the development of this metal oxide system with the adoption of a hard-template technique providing strict synthetic control of the porous morphology. It is found that through the variation of pore diameter, selectivity of CO2-derived products can be altered. Structural characterization of the synthesized metal oxide interfaces is complimented with electroanalytical experiments to evaluate changes in the local electrochemical environment and the relationship to reactivity. Finally, Chapter 4 outlines the synthesis of cyanide coordination polymers from octacyanometallates toward an assortment of materials that include metal carbides, alloys, oxides and phosphides. Similar to a template based syn- thesis, these materials retain their unique morphology, which includes catalytically relevant porous structures.
