Thermal decomposition of energetic materials using TG-FTIR and TG-MS: a state-of-the-art review

Applied Spectroscopy Reviews, Journal Year: 2019, Volume and Issue: 55(8), P. 724 - 777

Published: Oct. 23, 2019

Energetic materials have been widely investigated experimentally and theoretically for decades, but there are still many unanswered questions concerning their thermal decomposition mechanisms that play a key role in the overall reaction processes. Hyphenated analytical techniques of analysis, such as thermogravimetry coupled either with infrared (TG-FTIR) or mass spectroscopies (TG-MS) revealed to be efficient methods studying mechanisms. These allow exploration evolved gases during decomposition, which let trace back chemical allows better control behavior various energetic formulations. In this overview, classification, characterization properties material introduced. Next, advances application two hyphenated (TG-FTIR TG-MS) along appropriate examples discussed. offer remarkable improvements by enhancing amount authentic information obtained reproducibility compared conventional techniques. This first review article dedicated solely TG on-line an IR MS spectrometer, means heater transfer line, will certainly help researchers easily understand well development new applications.

Interaction Between Prussian Blue Ultrathin Nanosheet and Ammonium Perchlorate for Highly Efficient Thermal Decomposition

Advanced Functional Materials, Journal Year: 2023, Volume and Issue: 33(21)

Published: Feb. 23, 2023

Abstract Catalytic stability is the prerequisite for catalyst to achieve high catalytic efficiency. This study finds a new path that Prussian Blue (PB) ultrathin nanosheet assembly material (PB‐NSa) designed and used reach efficient catalysis through continuous interaction with ammonium perchlorate (AP, component be catalyzed). Based on strong oxidation environment provided by AP, decomposition of PB occurs in advance, product Fe 2 O 3 accelerates AP can release large amount gas, then reacts disperses it near undecomposed finally realizing catalysis. The results show under PB‐N, “deactivation” stage thermal disappears, showing two consecutive exothermic stages, temperature peak reduced 341.1 °C, reduction range 73.1 °C. Combining kinetic calculation TG‐IR test, found PB‐NSa keep excellent stability, which depends its special structure AP. research provides design idea will greatly promote rapid industrialization.
