Abstract Achieving high energy release of aluminum (Al) and ammonium perchlorate (AP) is significant importance in the realm materials. In this work, integrated Al@AP/GO‐CHZ‐M (M = Co 2+ or Ni ) composites are successfully synthesized through an design precise catalysis approach. The Al@AP/Co exhibit fast decomposition, with a 76.6 °C reduction decomposition temperature 66.0% increase heat compared to Al+AP mixture counterpart. From kinetic perspective, activation for largely decreased by 215.5 kJ mol −1 (−67.4%) its kinetics shifted autocatalytic model. Transition metals GO‐CHZ‐M facilitate proton transfer during AP, significantly increasing yield low‐valence nitrogen oxides. ignition Al@AP/M enhanced, 37.2 ms (−40.2%) delay 6.6‐fold radiation intensity over Al+AP. change from deflagration physical detonation further suggests release. Furthermore, mechanism on enhancement Al@AP elucidated. This approach holds broad application prospects fields solid propellants, aluminized explosives, micro‐thrusters, pyrotechnics systems.
