Two-dimensional nanoscale MoS2 for thermal catalysis of dihydroxylammonium-5,5′-bistetrazole-1,1′-diolate (TKX-50)

In situgeneration of a Ti3C2Tx(Tx= F, O and OH) MXene decorated CuO nanocomposite with extraordinary catalytic activity for TKX-50 thermal decomposition

“…The results showed that the main gas products of TKX-50 were ammonia, H 2 O, N 2 /CO, N 2 O and CO 2 according to different m / z values ( m / z = 17, m / z = 18, m / z = 28, m / z = 30 and m / z = 44), which were consistent with those reported in the literature. 24,47,48 In the TG-MS curve with the addition of I-Ti 3 C 2 T x /CuO, the mild peak of each m / z during decomposition became sharper and earlier with increased intensity compared with pure TKX-50, indicating that I-Ti 3 C 2 T x /CuO accelerated the release of gaseous products during TKX-50 pyrolysis and made TKX-50 decompose more rapidly.…”

“…TKX-50 is initially decomposed by heating to BTO and hydroxylamine, then the intermediate ABTOX (intermediate products of the TKX-50 decomposition process) is formed and finally H 2 O, N 2 , N 2 O, CO 2 , CO, NO, NH 3 and other catalytic products are produced. 41,47 The presence of Ti 3 C 2 T x MXene influences the bond energy of the TKX-50 molecule, which makes it easier to break and accelerate the decomposition reaction process with good catalytic effect. In this context, I-Ti 3 C 2 T x /CuO has a better synergistic catalytic effect than MXene and CuO, and its presence accelerates the transfer of H+ even more and the generation of gas products, thus reflecting the excellent catalytic effect.…”

Synthesis, characterization, and catalytic behaviour of nano‐bimetallic nickel oxide on the thermal decomposition of dihydroxylammonium‐5,5′‐bistetrazole‐1,1′‐diolate

“…The use of catalysts to improve the thermal performance of energetic materials is an important and versatile method; in it, a suitable catalyst is introduced to significantly reduce the thermal decomposition temperature and the activation energy of solid propellants, and to shorten the ignition delay time, thus improving their combustion rate. 9,10 The transition metal oxides investigation of combustion catalysts is crucial for the catalysis of TKX-50 thermal decomposition; the introduction of metal elements in combustion catalyst can improve the catalytic performance of the catalyst. The preliminary study, Fe exhibited excellent catalytic activity for thermal decomposition of energetic ionic salts, including TKX-50.…”
