A novel metal-organic framework precursor strategy to fabricate sub-micron CuO microspheres for catalytic thermal decomposition of ammonium perchlorate

Understanding the synergistically enhanced thermocatalytic decomposition of ammonium perchlorate using cobalt nanoparticle-embedded nitrogen-doped graphitized carbon

“…S9a, ESI†). Due to the content of catalyst in AP having a significant effect on reducing the HTD temperature, 48,49 the catalytic decomposition process of AP with 2, 4, 6, 8, and 10 wt% Co-NPs@NC- T was explored (Fig. 3a and Fig.…”

Zeolite Imidazolate Frameworks-67 Precursor to Fabricate a Highly Active Cobalt-Embedded N-Doped Porous Graphitized Carbon Catalyst for the Thermal Decomposition of Ammonium Perchlorate

“…Finally, a gas-phase reaction dominates, which converts the intermediate product and AP into small gas molecules in the HTD stage. 44 To further analyze the composition of the gas generated during the AP thermal decomposition process, thermal gravity analysis-Fourier transform infrared (TGA-FTIR) spectroscopy is frequently used as an analytical tool to detect AP decomposition gas products in real time. The three-dimensional (3D) FTIR spectrum of the thermal decomposition of AP with 10 wt % Co@NC demonstrated that AP began to violently decompose between 300 and 400 °C, producing a large number of gas products, and obvious strong absorption peaks appeared in the fingerprint region of the FTIR spectrum (Figure 3a), which were attributed to the LTD and HTD decomposition stages of AP.…”

“…Then, AP mainly undergoes a gas–solid two-phase reaction in the LTD stage, generating the intermediate products HClO 4 and NH 3 , which are adsorbed on the solid AP crystal lattice as gases. Finally, a gas-phase reaction dominates, which converts the intermediate product and AP into small gas molecules in the HTD stage …”

ZIF-8 derived ZnO: a facile catalyst for ammonium perchlorate thermal decomposition

“…The results show that by adding 10 wt% CuO, both decomposition temperature and E a values were significantly reduced. 17 Similarly, CuO-MOF derived Cu/Cu 2 O/C synthesized by Yan et al was found to be a promising catalyst for AP thermolysis due to its abundant pore structure and good synergy between Cu nanoparticles and the carbon present. 18 Likewise, flexible iron-based MIL-88B and Cu( ii )–MOFs were also employed as catalysts for AP pyrolysis studies.…”
