a Determined by XRF.
The metal content in the catalyst was derived from the XRF measurements and is listed in Table 1.As can be seen from Table 1,the content of alkali metals and the Co/Cu molar ratio were in close agreement with the nominal compositions used for preparing the catalysts,indicating that there were no obvi‐ous metal losses.Additionally,the added alkali metals may exist in the form of carbonates under the reduction conditions at 350°C due to the much higher decomposition temperature of car‐bonates,which can be seen from the TG curves of those sam‐ples(Fig.S1).The Li NO3 promoter may decompose into an oxide during the reduction process(350°C),while lithium ox‐ide would be easily converted to carbonate under a CO2 at‐mosphere because the Gibbs free energy for this reaction is negative.
