The performance of Cu/ZrO2 and Cu-La2O3/ZrO2 at different temperature was studied. The activity of both increased first and then decreased with the calcination temperature increased. This was due to the change of the copper dispersion and the interaction between copper and zirconia.

Key words: Cu/ZrO2, Cu-La2O3/ZrO2, Calcination temperature, Methanol synthesis
