- Abstract
To investigate the influence of microreactor on the synthesis of nano-combustion catalysis, the nano copper 2,4-dihyoxybenzoicacid catalysis were synthesized with Cu/NO3)2, and 2,4-dihyoxybenzoicacid as primary substances by using as star-type microreactor. The obtained samples were characterized by laser size analysis (LSA), X-ray diffraction (XRD), N2, adsorption-desorption, scanning electronic microscophy (SEM), and thermogravimetric analysis(TG). The effects of the preparation conditions on the average particle size, crystal type. SBET and morphology of the catalysts were also studied. The results show that the morphology of the catalyst presents a regular-shaped sheet when the preparation conditions are at room temperature, and the better velocity of flow of the microreactors is 1mL/min, and the mixed time is 15 min. The catalyst sheet with a size of 100nm and a specific surface area of 21.626 m²/g was obtained. The DSC results showed that the copper 2,4,dihydroxybenzoate- 15 with the mixing timeof 15 min reduced the peak temperature decomposition of RDX from 242.3 °C to 239.1°C, which indicates that the catalyst exhibits better catalytic efficiency for thermal decomposition of RDX.
