- 요약Global warming and associated climate change effects are the defining issue of the 21st century and decarbonization of all sectors is imperative to mitigate the worst consequences of climate change. Of particular importance are new, cost-effective, and greenhouse-gas-emissions-free chemical transformation processes to convert CO2into chemicals, fuels, and materials. This is in contrast to today's processes for producing chemicals, fuels, and materials, as nearly every such process produces direct and/or indirect CO2emissions. As a result, the paradigm shift that needs to occur is the transition from fossil-based sources for chemicals, fuels, and materials production to the use of CO2itself to produce these products, as this would allow for negative emissions by sequestering CO2in solid form.However, due to CO2's negligible value from a thermodynamic standpoint; nearly every CO2transformation is endothermic, requiring energy. This required energy can take the form of clean, emissions-free electricity obtained from solar and wind, for example, but widespread proliferation of renewable sources of electricity generation has yet to occur and the challenge of grid-scale energy storage has not yet been adequately addressed. A better alternative for this required energy exists in the form of a co-reactant with high enthalpy, such as CH4. CH4is arguably the most advantageous co-reactant due to its abundance and relatively low cost. Therefore, CH4and CO2are expected to be the feedstocks of the future to produce fuels, chemicals, and materials.Three such processes to transform CO2and CH4to chemical and fuels are discussed at length in this dissertation: 1) low temperature CO2utilization via reverse water-gas-shift chemical-looping, 2) CH4pyrolysis for the production of CO2-free H2and carbon nanotubes, and 3) photocatalytic direct CH4to CH3OH.
