We report a simple and effective method to produce copper‐doped carbon aerogel (Cu‐CA) using sodium alginate as a carbon precursor through ion crosslinking and high‐temperature carbonization. Results indicate that Cu‐alginate has a 3D scaffold structure with pores. The effect of using different metal salt mass ratios of Cu‐CA on the catalytic thermal decomposition of AP is also investigated. The thermal decomposition temperature of AP decreases by 94.24 °C, and the activation energy of the decomposition reaction is reduced by 45.7 kJ/mol. These results demonstrate that the composite exhibits superior catalytic performance compared with a single‐component transition metal salt.
