مروری بر کاربرد نانو کاتالیست‌های اکسید فلزی برای تجزیه حرارتی آمونیوم پرکلرات (علمی-ترویجی)

In this review, an attempt to collect summarized literature data on catalytic effect of nanosized metal oxides on the thermal decomposition of ammonium perchlorates is made. Several experimental results show nanometal oxides are more effective catalysts as compared to nanosized metals. Nanocatalysts decrease the activation energy and the increase the rate the thermal decomposition of ammonium perchlorate. The mechanism of catalytic action was based on the presence of superoxide ion O_2^- on the surface of nanocatalyats. The mechanisms of thermal decomposition which influence on the thermal decomposition of ammonium perchlorate are discussed.
