摘要：
This work was aimed to identify the influence of different titanium sources, namely nano-sized Degussa TiO2 (commercially known as P25), TiCl3, TiF4, and (NH4)(2)F6Ti, on the crystallization of micropoprous titanosilicate ETS-10. The characterization results of XRD, FESEM, Raman, and FTIR showed that the morphology, particle size, and purity of the final products were strongly dependant on the titanium sources because of the different crystallization mechanisms of ETS-10 in the presence of different titanium precursors. The different coordination states of Ti atoms and anions of the titanium precursors were observed to play a role in the formation of ETS-10.
