Abstract


The content of this thesis are: the analytically pure TiO 2 < / sub > , NbO 5 < / sub > and the K 2 < / sub > the CO 3 for raw materials , the use of high-temperature solid state reaction the niobate KTiNbO has a layered structure 5 < / sub > . Then KTiNbO 5 H exchange , organic amine treatment modified to increase KTiNbO 5 < / sub > of the layer spacing . Finally hydrothermal synthesis method is introduced to the interlayer , KTiNbO 5 metal oxides and hydroxides prepared by the intercalation compound . Designed to study KTiNbO 5 intercalation compound as the precursor synthesis , as well as mining these intercalation compounds potential application value to further expand KTiNbO 5 < / sub > the application . System discussed in the raw materials KTiNbO 5 H exchange reaction , the organic amine treatment response and intercalation reaction and arrive at the optimal reaction conditions for each step . Application hydrothermal synthesis method , inserted through the layer to KTiNbO 5 Magnesium Hydroxide the intercalation compound magnesium , titanium , niobium and oxygen ( MgTiNbO ) , the chemical formula [ Mg ( OH ) 0.185 < / sub> (H 2 O) 1.815 ] 0.551 · (TiNbO 5 ) · 2.468H 2 < / sub > O , the compound having a double lattice structure , and having fluorescent properties . Application hydrothermal synthesis method , 5 layer inserted between KTiNbO the MnOx synthesis of the intercalation compounds of manganese , titanium , niobium and oxygen ( MnTiNbO ) , the chemical formula [MnO 0.371 (H < sub> 2 O) 1.629 ] 0.307 · (TiNbO 5 ) · 0.275H 2 O and structure of this compound , the composition was analyzed. The product obtained by powder X-ray ( XRD ) , differential thermal - thermal gravimetric analysis ( DTA - TG ) , scanning electron microscopy ( SEM ) , transmission electron microscopy ( TEM ) , selected area electron diffraction ( SAED ) means to carry out a series of characterization .
