摘要：

一种中孔硫酸化的、只含Brø；nsted酸位的氧化锆-氧化硅催化剂可将甘油转化为丙烯醛，其产率和选择性分别为81%和82%.即使在低温（523 K）下，产物时空收率可高达9.0 mmol h-1 gcat-1.本催化剂的活性和选择性高于典型的硫酸化的ZrO2催化剂.氧化硅稀释了锆物种而使得催化剂酸性更温和，较大的孔径使得传质更快，因此催化剂性能提高.

Abstract:

A mesoporous sulfated zirconia-silica catalyst bearing only Brønsted acid sites converted glycerol to acrolein in 81% yield with 82% selectivity. Space time yield as high as 9.0 mmol h-1 gcat-1 was achieved even at a low reaction temperature of 523 K. The catalytic activity and selectivity were higher than those of typical sulfated zirconia. It is proposed that the milder acidity due to dilution of zirconium species by silica and large pore size for faster diffusion contributed towards the better catalytic performance.
