Catalytic Thermal Decomposition of Ammonium Perchlorate Using Cu/Cr Hydrotalcite Derived Nanocomposite Oxides

Article Preview

Abstract:

A series of Cu/Cr nanocomposite oxides (Cu/Cr–NCOs) were prepared by Cu/Cr hydrotalcite precursors. Their catalytic activities on thermal decomposition of ammonium perchlorate (AP) were investigated by differential thermal analysis (DTA). The results show that Cu/Cr–NCOs are efficient in enhancing thermal decomposition of AP. With 4 wt. % addition of 500 °C calcined Cu2Cr–NCOs, the thermal decomposition process of AP can be accelerated by 107 °C. Cu/Cr–NCOs catalysts have better effect compared to mechanical mixture of CuO and Cr2O3 catalyst. Their catalytic mechanism was also discussed.
