Since the middle of the 1990s, methanol synthesis via CO
2 hydrogenation has been studied as a key process for the methanol-based economy. Because of the reactivity difference between CO and CO
2, new catalysts specific to CO
2-to-methanol hydrogenation should be developed. Among the supports, ZrO2 is particularly promising because ZrO
2-containing catalysts led to highly active, selective and stable catalysts. In this study, we examined the effect of preparation condition of Cu/ZrO
2 catalysts on CO
2-to-methanol hydrogenation.
