| Abstract: 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. |
