PC载体铁基单原子催化剂的制备与催化性能
Preparation and Catalytic Performance of Fe Single-atom Catalysts Anchored on PC Carriers
摘要
Abstract
To develop efficient Burning rate catalyst(BRC),a key component for regulating solid propellant combustion perfor-mance,and to explore the role of single-atom catalysts,a Fe single-atom catalyst supported on porous carbon carrier(Fe-NC@PC)was designed and synthesized.The composition and morphology were thoroughly characterized by X-ray powder diffractometer(XRD),X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM),transmission electron mi-croscope(TEM),high-angle annular dark-field scanning transmission electron microscope(HADDF-STEM)and X-ray absorption fine structure(XAFS).Moreover,the effect of Fe-NC@PC on thermal decomposition for energetic materials within solid propel-lant was investigated via thermogravimetric-differential scanning calorimetry(TG-DSC).Results show that Fe atoms in Fe-NC@PC were anchored on the carrier surface via Fe-N bonds with the loading amount of 0.98%.Upon the addition of 5%Fe-NC@PC,the thermal decomposition peak temperature of 1,1-diamino-2,2-dinitroethylene(FOX-7),cyclo-1,3,5,7-tetra-methylene-2,4,6,8-tetranitramine(HMX),hexanitrohexaazaisowurtzitane(CL-20)and Dihydroxylammonium 5,5'-bistetra-zole-1,1'-diolate(TKX-50)decreased by 34.6,9.4,6.3℃and 27.9℃,respectively,demonstrating clear catalytic effects.Addi-tionally,the apparent activation energies were also altered.关键词
