摘要：
Ni/Co/Cu/Fe nano-composite oxides (Ni/Co/Cu/Fe-NCOs) were prepared by calcination of Ni/Co/Cu/Fe hydrotalcites (Ni/Co/Cu/Fe-HTs) precursors. Ni/Co/Cu/Fe-NCOs were used as new catalysts on improving thermal decomposition of ammonium perchlorate (AP). Their catalytic activities were investigated using DTA and TG-MS. The results revealed that Ni/Co/Cu/Fe-NCOs exhibited NiO and spinel phase with high specific surface areas of 90-120 m(2) g(-1). They have homogenous particles with average crystallite size in the range of 50-60 nm. The thermal decomposition process of AP can be accelerated by the addition of Ni/Co/Cu/Fe-NCOs. Ni/Co/Cu/Fe-NCOs achieved the purpose of improving thermal decomposition of AP based on the presence of superoxide ion (O-2(-)) on the surface of Ni/Co/Cu/Fe-NCOs.
