钛酸锌的制备及其对高氯酸铵热分解的催化性能

ZnTiO₃ nanocrystals were prepared by sol-gel method, using Zn(NO₃)₂ and Ti(C₄H₉O)₄ in the topic. The as-prepared ZnTiO₃ nanocrystals were characterized by XRD, FTIR and TEM, and the catalytic performance of ZnTiO₃ nanocrystals of different contents for the ammonium perchlorate(AP)decomposition was investigated by thermal analysis. The results indicate that ZnTiO₃ with pure cube structure can be synthesized at 600 ℃ by this procedure，which was spheroid with particle size of about 60~100 nm. The results expressed that the low temperature decomposition peaks of AP is advanced by 17 ℃ and the high temperature decomposition peaks of AP is advanced by 24 ℃ when adding 5% nanoparticle ZnTiO₃ powder. The catalytic effects of ZnTiO₃ powders on the high temperature decomposition of AP are less than that of nanometer metal powders, but all the micron metal powders decrease the low decomposition temperature of AP.
