摘要: 以阴离子表面活性剂为模板剂,硝酸铝为铝源,氯化镍为镍源,水热超声法合成镍铝复合介孔氧化物。当n(Ni)/n(Al)=1∶7,反应温度80℃,反应时间28h,晶化12h,样品有较规则的介孔结构。用X射线多晶衍射(XRD)、红外光谱(IR)、N2吸附-脱附、NH3和CO2程序升温脱附(NH3-TPD和CO2-TPD)、程序升温氧化还原(TPO和TPR)等方法对样品进行了表征。结果表明,样品具有典型的介孔结构特征,孔径分布较窄,平均孔径2.6nm,孔容积0.216cm3/g,比表面积为297.132㎡/g。样品具有弱和强的酸碱中心,340℃可被氧化,430℃可被还原。

Abstract:

Mesoporous Ni/Al composite oxides were synthesized by hydrothermal ultrasonic reaction using anionic surfactant as templating agent, Al(NO3)3·9H2O as aluminium source and NiCl2·6H2O as nickel source. The samples appear  mesoporous phases when the n(Ni)/n(Al)=1∶7, reaction temperature 80 ℃, reaction time 28 h, crystallization of 12 h. The samples were characterized by XRD, FT-IR, N2  adsorption-desorption, NH3-TPD, CO2-TPD, TPR,TPO and so on. The experimental results indicate that samples exhibit typical mesoporous structural characteristics with a narrow distribution of pore size, average pore size is 2.6 nm, pore volume is 0.216 cm3/g, surface areas is 297.132 m2/g. The samples exhibit weak and strong acid-base center,at same time, could been oxidized at 340 ℃ and reduced at 430 ℃.
