Atomic‐Layer‐Deposited ZnO on Carbon Black as High‐Performance Catalysts for the Thermal Decomposition of Ammonium Perchlorate

Abstract: Hybrid materials with ZnO anchored on carbon black (CB) are fabricated by using the atomic‐layer deposition (ALD) technique. The oxygen‐containing functional groups on the surface of the CB act as the reactive sites to facilitate stable deposition of ZnO, and further create a unique hybrid structure with a C–O–Zn bond between CB and ZnO. The catalytic performance of the ZnO/CB hybrids for thermal decomposition of ammonium perchlorate (AP, NH4ClO4) is investigated, showing that two exothermic peaks are merged i… Show more

“…Moreover re‐accepting the released electrons by the NP‐PANi helps the more and more dissociation of HClO 4 species to produce further O − (Figure ). Thus, the NH 3 ‐covered surface formation will be omitted.This is the reason that NP‐PANi can act as a green catalyst and increase the maximum decomposition rate and the total heat release of AP, drastically …”

“…For the decomposition process of pure AP at the heating rate of 10 ℃/min, the endothermic peak due to AP changes from orthorhombic to cubic crystal forms [9] was at 245±3 ℃, exothermic decomposition peak due to the low temperature decomposition (LTD) [10,11] was at 301 ℃, and high temperature decomposition (HTD) peak [12,13] was at 392 ℃. With the addition of quaternary ammonium salt, the LTD and HTD processes of AP in pure AP curves and AP/PBT propellant have both significantly changed.…”

“…Owing to the presence of various surface oxygen‐containing functional groups, carbon particles are able to form chain network patterns, which provide the uniform distribution of catalyst particles in a polymer matrix and increase its thermal conductivity [38]. Wang investigated the catalytic activity of the ZnO/CB catalyst which was fabricated by using atomic layer deposition technique on the thermal decomposition of ammonium perchlorate [39].…”
