Ferric oxide colloid: novel nanocatalyst for heterocyclic nitramines

摘要: Highly energetic nitramines such as cyclotetramethylene-tetranitramine (HMX) experience high combustion enthalpy, well large volume of gaseous products. Despite the fact that HMX can expose thermal stability, it exposes low sensitivity to different catalysts. HMX-based propellants will combust at burning rate. Ferric oxide particles with hydrous surface offer catalyzing ability via release active .OH radicals; species would attack heterocyclic ring hydrogen atom abstraction. crystalline, monodispersed Fe2O3 nanoparticles (NPs) 3.39 nm average particle sizes were developed using hydrothermal processing. Fe2O3NPs integrated into co-precipitation technique. The impact (1 wt%) on thermolysis was investigated differential scanning calorimetry (DSC) and gravimetric analysis (TGA). demonstrated advanced catalytic performance. main exothermic decomposition peak decreased by 13.0 °C an increase in enthalpy 72.2%. could alter from C–N cleavage abstraction through released radical. Additionally NO2 be adsorbed nanocatalyst offering enthalpy.
