Electrochemical reduction of carbon dioxide to formate in a flow cell on CuSx grown by atomic layer deposition
Abstract
<p>Transition metal chalcogenides (TMCs) are promising pre-catalysts for tuning the selectivity of electrochemical carbon dioxide (CO<sub>2</sub><sub>)</sub> reduction (CO2R). Atomic layer deposition (ALD) enables well-controlled growth of thin TMC films on various gas diffusion electrodes. Herein, we have studied the CO2R performance of ALD-grown copper sulfide (CuS<sub>x</sub>) in a flow cell. The effects of electrode configuration, electrolyte concentration, temperature, and electrolysis time were carefully studied, combined with pre- and post-electrolysis physico-chemical analyses of the films. The unique selectivity of sulfur-doped Cu towards formate was retained with Faradaic efficiencies between 40 and 60%, but slow selectivity changes were observed over time. Major loss of sulfur was encountered during the initial 5-min reduction period, and after that, progressive formation of nanoparticles could be observed. Comparisons to ALD-grown Cu thin film and CuS<sub>x</sub>-modified Cu foam electrodes verified the importance of sulfur and suggested that other electrocatalyst films could be easily realized with ALD.</p>
