Abstract:
？以含巯基官能团有机硅烷修饰的介孔材料MCM-41和SBA-15为载体,采用浸渍-氢气还原法制备了高分散和高活性的负载型Pd催化剂.X射线衍射、N2吸附-脱附和透射电子显微镜表征结果显示,所制Pd催化剂Pd-SH-MCM-41和Pd-SH-SBA-15具有很好的长程有序结构、分布均匀的孔径、高比表面积及高度分散的Pd颗粒.苯酚加氢反应结果表明,以Pd-SH-MCM-41和Pd-SH-SBA-15为催化剂时,在80℃,1.0MPa反应1h,苯酚转化率达99%以上,环己酮选择性为98%.它们的催化活性为商业Pd/C催化剂的5倍,Pd/MCM-41和Pd/SBA-15催化剂的3倍.这可归因于介孔材料表面修饰的巯基官能团对Pd的锚定作用,避免了Pd颗粒的团聚,使其高度分散在介孔材料上.
