The physical properties and morphology of synthesized samples were examined by various
techniques. The study of crystallinity was conducted by an X-ray diffractometer (Miniflex
goniometer) using CuKα radiation in angular range from 1 to 10 °(2θ) with 15 mA and 30 kV.
The surface morphology was studied by SEM (JEOL JSM-6400) operated at 15 kV and TEM
(JEOL-JEM-200 CX) operated at 100 kV. The porosity was determined by the nitrogen adsorption
data (Autosorb-1, Chrantachrome) and surface area and pore size distribution were calculated on a
basis of the BET method and the BJH model.
