以石墨烯为载体,采用两步法制备了CuCr2O4/石墨烯复合粒子,通过X射线衍射仪(XRD)、透射电子显微镜(TEM)对样品的结构及形貌进行了表征,并采用差示扫描量热仪(DSC)分别研究了CuCr2O4、CuCr2O4/石墨烯、石墨烯及CuCr2O4和石墨烯的混合物对AP的催化效果。结果表明,CuCr2O4纳米粒子较均匀地分布在石墨烯上,CuCr2O4/石墨烯复合粒子使AP高温分解峰温度降至382℃,降低了60℃,表观分解热增加了351J/g,达1188J/g,其催化效果明显优于CuCr2O4、石墨烯及CuCr2O4和石墨烯的混合物。
Graphene was used as a carrier to prepare CuCr2O4 / graphene composite particles by two-step method. The structure and morphology of the samples were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM) The catalytic effect of CuCr2O4, CuCr2O4 / graphene, graphene and a mixture of CuCr2O4 and graphene on the AP was studied by calorimeter (DSC). The results showed that the CuCr2O4 nanoparticles were distributed more evenly on the graphene. The CuCr2O4 / graphene composite particles decreased the pyrolysis peak temperature of AP to 382 ℃, decreased 60 ℃, and the apparent decomposition heat increased by 351J / g, reaching 1188J / g, the catalytic effect is significantly better than CuCr2O4, graphene and CuCr2O4 and graphene mixture.
