摘要:<正>Selective reduction of crotonaldehyde over Zr-MCM-41 catalysts prepared by grafting method was investigated.Effect of pre-evacuation of MCM-41 before Zr-grafting on the activity of Zr-MCM-41 was studied. The catalysts prepared by grafting method indicated both high dispersion of Zr oxide on MCM-41 and high activity.The pre-evacuation of MCM-41 controlled surface concentration of hydroxyl group and strongly affected the dispersion of Zr oxide on MCM-41.
