Hollow Cu2O/CuO nanocomposites via hydrothermal synthesis toward enhancing the thermal decomposition of energetic molecular perovskite

This investigation examines the thermocatalytic behavior of hollow Cu 2 O/CuO nanocomposites toward a molecular perovskite energetic material. The incorporation of hollow Cu 2 O/CuO nanocomposites at weight percentages of 1 %, 5 %, and 10 % consistently reduced the peak thermal decomposition temperature ( T p ) compared to pure DAP-4. Specifically, the T p values decreased by 50.70 °C, 76.98 °C, and 78.46 °C, respectively. This enhanced thermal stability was accompanied by a corresponding decrease in activation energy values, which were lower by 115.9 kJ/mol, 200.57 kJ/mol, and 209.98 kJ/mol, respectively. Base on the findings, we proposed a possible catalytic decomposition mechanism of DAP-4 mediated by hollow Cu 2 O/CuO nanocomposites.
