摘要:
以无机盐为原料通过控制pH值,用水热法合成含Ni皂石,并以此皂石为前驱物、十六烷基三甲基溴化铵为模板剂,制备含Ni介孔分子筛。用X射线粉末衍射、Fourier变换红外光谱、程序升温还原、透射电子显微镜、比表面积和孔径测定等仪器和方法表征样品的物化性能。结果表明:制得了有序性好的含Ni介孔分子筛,其比表面积为811.2m2/g,平均孔径为3.64nm。所制备的含Ni介孔分子筛经850℃焙烧3h或100℃水热处理10d后仍然具有介孔结构,说明样品具有高的(水)热稳定性。

Saponites with Ni were synthesized by a hydrothermal method with inorganic salts as the raw material and with a con- trolled pH value. Then mesoporous molecular sieves with Ni were synthesized by the hydrothermal method with the above synthe- sized saponites as precursors and cetyl trimethyl ammonium bromide as template agent. The samples were characterized by X-ray diffraction, Fourier transform infrared spectra, temperature programmed reduction, transmission electron microscope, nitrogen ad- sorption surface area and porosity measurements. The results show that a highly ordered mesoporous molecular sieve with Ni is ob- tained with specific surface area of 811.2 m2/g and the average pore diameter of 3.64 nm. The prepared mesoporous molecular sieves with Ni still has a mesoporous structure after calcination at 850 ℃ for 3 h or hydrothermal treatment at 100 ℃ for 10 d. It is con- cluded that the obtained samples have high thermal and hydrothermal stability.
