| Abstract | Abstract A series of Zr-containing catalysts including bulk ZrO 2 , ZrO 2 supported on silica, titania and ceria, Zr-BEA zeolite and Zr-MCM-41 mesoporous material was prepared and characterized by X-ray diffraction, nitrogen adsorption-desorption, X-ray photoelectron spectroscopy, 29 Si MAS NMR, TPD NH 3 , and FTIR of adsorbed CO. The catalytic materials were tested in the MPVO reaction of crotonaldehyde and ethanol in the temperature range of 473–573 K. The results showed that the activity of Zr-based catalysts in the MPVO reduction of crotonaldehyde correlates with the amount of Zr 4+ Lewis acid sites in the catalysts. Tetrahedral Zr atom sites isolated within the crystalline structure of zeolite BEA were found to be the most efficient. The best catalyst performance in terms of selectivity was observed over ZrBEA: 72% selectivity to crotyl alcohol was achieved at crotonaldehyde conversion of 15%. |
