Abstract

The electrochemical conversion of carbon dioxide to solid carbon using four electrode materials (Ag, Pt, Ni, and Ir) in Li–K molten salts was investigated. The current-time plots indicate that the current in the Ag electrode is higher than that in the other electrodes owing to its high reactivity. Over 12 h, the current gradually increased for the Ag and Ni electrodes, whereas it decreased for the Pt and Ir electrodes. The TG and DTG results showed all carbon samples have similar thermal reactivity, and low crystallinity compared to graphite. The XRD results revealed that the solid carbon produced on the Ag and Pt electrodes had a low crystallinity index because the samples that exhibited high reactivity had a low crystallinity index. The carbon produced on the Ag electrode contained Ag due to corrosion of the electrode in the molten carbonate. According to the SEM images, the nanoparticle sizes of Ag and Pt are smaller than those of Ni and Ir. Many shell shapes are formed from a reaction between CO2 and CO; this reduces the efficiency of carbon production. Comparing the characteristics of the produced carbon, Pt is a suitable material for this system, considering the reactivity and durability.
