In situ TR-XRD and in situ XPS results confirm that La2O3 presence promotes the formation of Co2C phase during carburization of CO, especially maximized at the La2O3 loading of 0.5 wt%. Moreover, Co-La(0.5wt%) sample has the maximum activity of CO and selectivity to C6+ alcohols. Therefore, it can be concluded that there is a close relationship between the Co2C formation during carburization and higher alcohol synthesis.
