摘要：以正硅酸乙酯和硝酸氧锆为原料，采用一锅法制备了不同 Zr/Si 物质的量比的 Zr-SBA-15 催化剂，借助
N 2 物理吸附、XRD、NH 3 -TPD、吡啶-原位红外光谱考察了 Zr/Si 物质的量比对 Zr-SBA-15 结构、织构、表面酸
性质及催化肉桂醛 Meerwein-Ponndorf-Verley（MPV）转移加氢性能的影响；探讨了 Zr-SBA-15 结构、织构及表
面酸性质对其催化肉桂醛 MPV 转移加氢性能的影响机制。结果表明，Zr-SBA-15 催化剂均呈现规整的介孔结构
特征，表面酸中心以 L 酸为主。随 Zr/Si 物质的量比增加，Zr-SBA-15 催化剂的最可几孔径逐渐减小，L 酸量持
续增加，B 酸量变化不大，肉桂醛转化率呈现先增加后趋于稳定的趋势，目标产物肉桂醇选择性增加，副产物
1-苯丙烯-2-丙基醚选择性下降。在 Zr/Si 物质的量比为 0.10 时，Zr-SBA-15 催化剂显示最优的催化性能，肉桂醛
转化率为 96.2%，目标产物肉桂醇选择性达到 95.2%，经 7 次循环后催化剂仍保持 90%以上的肉桂醛转化率和
95%以上的肉桂醇选择性。

Abstract: A series of Zr-SBA-15 catalysts with different Zr/Si molar ratio were prepared by one-pot
method using tetraethyl orthosilicate and zirconium dinitrate oxide as raw matrials. The effects of Zr/Si
molar ratio on the structure, texture, surface acidity and catalytic performance of Zr-SBA-15 catalysts for
the (Meerwein-Ponndorf-Verley) MPV transfer hydrogenation of cinnamaldehyde were investigated by means
of N 2 physical adsorption, X-ray powder diffraction, NH 3 temperature-programmed desorption and pyridine
in situ infrared spectroscopy. The results showed that all prepared Zr-SBA-15 catalysts exhibited regular
hexagonal mesoporous structure with L acid as main surface acid center. With the increase of Zr/Si molar
ratio, the most probable pore size of Zr-SBA-15 catalyst decreased gradually, the amount of L acid kept
increasing, while the amount of B acid changed lightly. The conversion of cinnamaldehyde initially
increased and then tended to be stable. The selectivity of the target product cinnamyl alcohol increased.
However, the selectivity of the by-product 1-benzene propylene-2-propyl ether decreased. When the Zr/Si
molar ratio was 0.1, the prepared Zr-SBA-15 catalyst showed the optimal catalytic performance. The
conversion of cinnamaldehyde reached 96.2%, and the selectivity of cinnamyl alcohol was 95.2%. After the
Zr-SBA-15 catalyst being recycled for 7 times, the conversion of cinnamaldehyde was still kept above 90%,
and the selectivity of cinnamyl alcohol was over 95%.
