(4hy) Solid Oxide Electrochemical Cells for CO2 Capture and Conversion

Research Interests: Increasing energy consumption, rising price of fuel associated with the depletion of fossil fuels, and the growth of CO₂ emissions all require the development of more energy-efficient processes and a shift from non-renewable energy sources to alternative/renewable energy sources. Here, we will present our development on the integrated intermediate-temperature operated solid oxide electrochemical cells with electrocatalysts for CO₂ capture and conversion, which can reduce the thermal budget, alleviate fast degradation at high temperature, and powerfully booster the product (high-value chemicals) yield (conversion and selectivity). Our approach involves material development and optimization on the catalyst composition and morphology to realize high CO₂ absorption and conversion efficiency. The investigation of the electrocatalysis property of the catalyst, which is studied by integrating into solid oxide electrochemical cells with applied voltage/current, will be presented. This work will pave the way for mitigating CO₂ emission from large industrial emission points to the air.
