【摘要】 采用正硅酸乙脂作为硅源,十六烷基三甲基溴化铵作为模板剂,采用摩尔配比为n(SiO2):n(CTAB):n(H2O):n(NaOH)=1:0.45:60:0.48,通过水热合成方法合成了MCM-48分子筛,通过用XRD、TEM(EDS)、DTA/TG、FT-IR、N2吸附脱附等对合成的样品进行了表征,经过BET算法得到的比表面为698.0693(m2/g),平均孔径3.46142nm。更多还原

【Abstract】 Using TEOS as silica source,cetyltrimethylammonium bromide as templating agent,MCM-48 molecular sieve was synthesized with the molar ratio of n(SiO2):n(CTAB):n(H2O):n(NaOH)= 1:0.45:60:0.48 by hydrothermal synthesis method,synthesized samples were characterized by XRD,TEM(EDS),DTA/TG,FT-IR and N2 adsorption-desorption,and the ratio surface area to volume is 698.0693(m2/g),and the average pore diameter is 3.46142nm through BET algorithm.更多还原
