Assembly of composites into a core–shell structure using ultrasonic spray drying and catalytic application in the thermal decomposition of ammonium perchlorate

The (3,5-DNB)FeCo and (3,5-DNB)FeCu micro-nanospheres with core–shell structure are prepared by ultrasonic spray drying. The DSC curves indicate that (3,5-DNB)M·M′s with various mixed ratio have different effects on AP thermal decomposition.
