dc.description.abstractModern society stands on fossil-fuel technologies. The electricity, heating, transportation, and entertainment derived from fossil fuels, while providing convenience to society, causes the CO2 concentration in the atmosphere to rise, creating the greenhouse effect on the planet. CO2 reduction reaction (CO2RR) is one of the potential methods to mitigate the greenhouse effect. Through CO2RR, CO2 can be transformed into energy carriers such as CO, CH4, C2H2, and others. Therefore, CO2RR can help to maintain the comfort of modern society while reducing the CO2 emission. This thesis is based on experimental CO2RR studies carried out on a solid-state ionic device built from a Y-doped BaZrO3 (BZY) perovskite. The main work is consisting of synthesis of BZY, construction of an anode-support proton conducting electrolysis cell (PCEC), X-Ray Powder Diffraction (XRD), Scanning Electron Microscope (SEM) characterization, and Electrochemical Impedance Spectroscopy (EIS) and high temperature CO2RR test. The results have shown that the CO2RR is feasible under the operating condition of the PCEC (350-450°C). Products including CO, H2 and CH4 were quantified using gas chromatography (GC). The project demonstrates the potential use of solid-state proton conductors for high-temperature CO2RR.
