제목 Off-grid electrocatalytic CO2 conversion system combined with As(III) oxidation
초록 Electrocatalytic CO2 conversion system combined with As(III) oxidation in single device is demonstrated. Prior to combination, each half-reaction was optimized under the same electrolyte, and it was demonstrated that the addition of chloride ion in the electrolyte enhances reaction rate both reactions. Especially in the case of As(III) oxidation, faradaic efficiency is greatly reduced because of competing with water oxidation reaction at high potential, and It is mitigated by reactive chlorine species which mediated to As(III) oxidation in bulk. Finally, this simultaneously electrocatalytic system was connected to a low-cost photovoltaic cell to drive off-grid system.

This research was supported by the Basic Science Research Program (2019R1A2C2002602 and 2018R1A6A1A03024962) and the Next-Generation Carbon Upcycling Project (2017M1A2A2043123) through the National Research Foundation, Korea.
