H2SO4 and Al2 ( SO4 ) 3 Modifying Mesoporous Molecular Sieves Al-MCM-41 and Their Catalytic Performances
用SO2-4物质的量相同的H2SO4和Al2(SO4)3分别对Al-MCM-41进行改性,得到样品SO2-4-/Al-MCM-41和Al/SO2-4/Al-MCM-41.采用X射线多晶衍射(XRD)、红外光谱(FTIR)、N2吸附-脱附和NH3程序升温脱附(NH3 -TPD)等测试技术对样品进行表征.分别用H2SO4、MCM-41、Al-MCM-41、SO2-4/Al-MCM-41和Al/SO2-4/Al-MCM-41催化合成丙酸香叶酯,比较了它…查看全部>>
The S042-/Al-MCM-41 and A1/SO42-/A1-MCM41 were prepared through modification of Al-MCM-41 with H2SO4 and Al2 ( S04)} with the same amounts of S042-, respectively. The structures of two samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) , N2 adsorption-desorption and NH3 temperature program desorption ( NH,-TPD). The catalytic performances of H2SO4, MCM41, Al-MCM-41, SO42-VA1-MCM41 and Al/SO42-/Al-MCM-41 were…查看全部>>
