“…They suggested that graphene nanosheets can promote hydrogen transfer from protonated H 2 DABCO 2+ to ClO 4− and catalyze the thermal decomposition of the material, due to a domino mechanism of combustion propagation by the graphene. [33] Shang et al studied five different metal-free perovskites, ANH 4 (ClO 4 ) 3 , where the A is changed, as high-energy materials. [21] The metal-free perovskites are comparable in their detonation parameters to some common high explosives, but with higher detonation temperatures.…”

“…Besides, the combustion performance and thermal decomposition of DAP-4 and AP/Dabco mixture were investigated by Deng et al, and the results showed that DAP-4 showed better thermal performance and higher energy release efficiency than AP/Dabco mixture during combustion [12]. To further improve the combustion performance of DAP-4, Deng et al prepared DAP-4/graphene composite and found that functionalized graphene was beneficial to improve the combustion performance of DAP-4 [13]. Moreover, after the addition of metal complex [14][15], graphene [16], metal-doped graphite carbon nitrite [17], and other catalytical components, the thermal decomposition performance of DAP-4 can also be enhanced, with significantly reduced thermal decomposition temperature and activation energy, and decreased ignition delay time of DAP-4.…”
