| 摘 要： | 以十六烷基三甲基溴化铵为模板剂,正硅酸乙酯为硅源,MCM-41为载体,碱性条件下,合成Pd/Ni-MCM-41。通过XRD、HR-TEM、FT-IR和BET等对Pd/Ni-MCM-41进行表征。Pd/Ni-MCM-41的比表面积为(444.32～621.69) m^2·g(-1),孔容为(0.54～0.69) cm^3·g^(-1),孔径分布均匀,主要集中在(2～4) nm。将Pd/Ni-MCM-41用于苯甲醛加氢制备苯甲醇反应中,Ni质量分数6%时,在反应温度100℃和反应压力0.20 MPa条件下反应2 h,苯甲醛转化率65.1%,苯甲醇选择性为100%。

| Abstract: | Pd/Ni-MCM-41 was synthesized under alkaline conditions with cetyltrimethylammonium bromide as template,ethyl orthosilicate as silicon source and MCM-41 as carrier,and characterized by XRD,HR-TEM,FT-IR,BET and so on.Results showed that specific surface area of Pd/Ni-MCM-41 was (444.32-621.69) m2·g-1,pore volume was (0.54-0.69) cm3·g-1,and pore size was (2-4) nm.When Pd/Ni-MCM-41 with Ni mass fraction of 6% was used in hydrogenation of benzaldehyde to benzyl alcohol,conversion of benzaldehyde was 65.1% and selectivity was 100% in 2 h under 100 ℃ and 0.20 MPa. |
