Preparation and Properties of Composite Nanoparticle MgO/SnO2

Abstract

Abstract: Composite nanoparticle MgO/SnO₂ was prepared by the coprecipitation method. The particle size, structure, phase
and composition of samples were characterized by TG, XRD, TEM and EDS. The catalytic activity of product on the thermal decomposition of RDX was
determined by DSC. The results show that average particle size of samples are about 3nm. Mg doping takes the role of improving the thermal stability,
and can enhance the catalytic activity of product. The samples can make the peak temperature of thermal decomposition of RDX decrease 8.5℃,
and make the decomposite enthalpy ΔH of RDX increase 518J·g^-1 (about50%).

Key words: MgO/SnO₂, composite nanoparticle, coprecipitation, catalyst
