PbSnO3@rGO纳米复合物的制备及其对CL-20热分解的影响
Preparation of PbSnO3@rGO Nanocomposite and Its Effect on the Thermal Decomposition of CL-20
摘要
Abstract
PbSnO3@reduced graphene oxide (PbSnO3@rGO) nanocomposite was prepared using a hydrothermal method and characterized by XRD and SEM.The catalytic effects of reduced PbSnO3-TDI (r-PbSnO3-TDI) and prepared PbSnO3@rGO on the thermal decomposition of hexanitrohexaazaisowurtane (CL-20) were analyzed by DSC method.The results show that rGO as substrate supported PbSnO3 can effectively solve the problem of aggregation of PbSnO3 nanoparticles and greatly improve the dispersion of nanoparticles.PbSnO3@rGO has good catalytic activity on the thermal decomposition of CL-20.PbSnO3@rGO makes the decomposition peak temperature of CL-20 reduce by 1.32℃,the apparent decomposition heat of CL-20 increase by 250J/g and apparent activation energy of the thermal decomposition of CL-20 decrease from 222.4kJ/mol to 181.1kJ/mol.Compared with r-PbSnO3-TDI,PbSnO3@rGO shows better catalytic effect on the thermal decomposition of CL-20.关键词
