small angle x-ray diffraction

Ordered porous titanium phosphate materials were prepared by use of template method combined with the acid-base theory. The samples were attained under the different conditions and were characterized by large and small angle X-ray diffraction, N2 adsorption/ desorption techniques.

运用模板法并结合酸碱对理论来合成多孔材料TiPOx，并对不同条件下所得到的TiPOx材料分别用广角X射线衍射、低角X射线衍射和N2吸脱附等实验进行了表征。
