“…In Figure 3a, the as-prepared catalyst was mostly present in Co 3 O 4 , where the peaks were assigned to a pure Co 3 O 4 phase. [38][39][40] The crystallite structure of the spent catalyst changed significantly with new diffraction peaks observed at 41, 47, and 76°2θ, corresponding to metallic Co (100), ( 101), (110), respectively, [41,42] while the peak at 44°2θ indicated the dominant Co 3 O 4 (404) phase. This confirms the change in the oxidation state of Co from higher one (Co 3 O 4 ) to lower one CoO x during the catalytic reaction under the reducing condition of RWGS and the applied polarization.…”

In this study, Copper-modified Co 3 O 4 (Cu/Co 3 O 4 ) catalysts were investigated for the reverse water gas shift (RWGS) reaction at 200-400 °C under different CO 2 : H 2 ratios. It was found that the electrocatalytic performance of Co 3 O 4 was improved by loading 4 weight percent (wt.%) Cu nanoparticles (average size: 13 nm), which could be then used as an electrode in electrochemical promotion of catalysis (EPOC) studies. Under the applied voltages of + 2 V and À 1 V, the catalytic rates were suppressed and increased by about 40 % and 14 %, respectively. This was due to the changes in the active oxidation states of Cu and Co caused by O 2À migration under polarization, as confirmed by XPS, XRD, and cyclic voltammetry (CV). The study also revealed that the exchange current density (i 0 ) was counter-correlated with the open-circuit catalytic rate (r 0 ) and could serve as an informative tool for predicting the catalytic rate, which was demonstrated for the first time in the instance of RWGS reaction.
