纳米NiO/MgO的制备及其对AP热分解催化性能影响
Preparation of nanometer NiO/MgO and its catalytic performance for thermal decomposition of ammonium perchlorate
摘要
Abstract
The nanometer NiO/MgO composite particles were prepared via impregnation method. The phase and morphology of NiO/MgO composites were characterized by X-ray diffraction, transmission electron microscopy and energy dispersive X-Ray spectroscopy. The catalysis of nanometer particles ( NiO, MgO), NiO + MgO mixture particles and NiO/MgO composite particles the thermal decomposition of ammonium perchlorate (AP) was investigated by DSC. The Results show that NiO particles are highly dispersed on the MgO support. Catalytic performance of the obtained nanometer NiO/MgO composite particles is superior to that of corresponding single ingredient and NiO + MgO mixture particles. Nanometer NiO/MgO can make the high-temperature decomposition peak value of AP decrease by 92.2 ℃ and the temperature difference value between the low and high temperature decomposition peak reduce up to 10. 6 ℃, which indicates good catalytic performance. The supporting effect of the nanometer MgO can effectively prevent the aggregation of NiO particles and increase the active sites.关键词
