Iron oxide‐filled multi‐walled carbon nanotubes (Fe 2 O 3 @MWCNTs) composite particles were produced by a mild and superior physical absorption method using molten Fe(NO 3 ) 3 ·9H 2 O as the precursor. Characterisation of Fe 2 O 3 @MWCNTs composite particles was performed by X‐ray diffraction, scanning electron microscopy, transmission electron microscopy and thermogravimetry‐differential scanning calorimetry. The results showed a large number of hematite phase Fe 2 O 3 were uniformly filled in the MWCNTs, and the mass fraction of Fe 2 O 3 was about 25.8 wt%. Furthermore, in the presence of 10 wt% Fe 2 O 3 @MWCNTs composite particles, the peak temperature of the high‐temperature decomposition of ammonium perchlorate (AP) decreased by 116°C, the peak of the low‐temperature decomposition disappeared and the amount of AP heat released was increased about 200 kJ/mol.
