Mesoporous Ni/Al composite oxides were synthesized by hydrothermal ultrasonic reaction using anionic surfactant as templating agent, Al(NO ₃) ₃·9H ₂O as aluminium source and NiCl ₂·6H ₂O 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, N ₂  adsorption-desorption, NH ₃-TPD, CO ₂-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 cm ³/g, surface areas is 297.132 m ²/g. The samples exhibit weak and strong acid-base center,at same time, could been oxidized at 340 ℃ and reduced at 430 ℃.

Lanthanum oxide/dodecyl sulfate mesoporous material (LaOS) was synthesized by hydrothermal method with SDS as template and ethylenediamine as medium. The experimental results indicate that the material had the ordered mesoporous pore structure when n(La)/n(SDS)/n(CO(NH ₂) ₂)/n(H ₂NCH ₂CH ₂NH ₂)/n(H ₂O)=1.0∶1.0∶0.6∶1.0∶200, stirring at 80 ℃ and 4 h using several measurements such as XRD, IR，TG/DTA,N ₂ adsorption-desorption .The results indicate that the material had the medial pore structure with average pore diameter of 2.6 nm and the specific surface area of 182 m ²/g. The LaOS materials were used as catalysts in the ethoxylation reaction. The results show that the material was highly catalytic activity. Experiment indicates that the optimum processing parameters are :120 ℃, 0.5 MPa,mass fraction of 10% catalyst (LaOS) and average reaction rate of epoxy ethane is 3.7 mol/(mol·h). And narrowed chain distributions of octanol polyoxyethlene were formed in the presence of LaOS catalyst.
