The performace of material was tested by DSC,XRD,SEM,EIS and charge-discharge cycles . The influences of various synthesized condition , sintering time and the amount of F were studied and correlative technics parameter to improve performance of material were optimized. DSC shows that three endotherimc peaks and one large exothermic peak are observed in the temperature range 150-400℃, which is because of the removal of water,the decomposition of the organic constituents and the formation of spinel. Only the citrate precursor is sintered at least 450℃, the crystallinity of spinel phase could be formed intactly.

The results indicated that the effect of pH on adsorption of theanine was not obvious within range of 6~11. The adsorption date fit well into the Freundlich and Langmuir isotherm equation within temperature range of 303~323 K and investigative concentration range. The isosteric enthalpy of adsorption, free energy and entropy of adsorption showed that adsorption of theanine was endothermic and spontaneous.
