中文摘要：

针对传统的湿法制备金属粒子修饰碳材料复合物对环境污染严重且不能大量生产等问题,采用干法制备金属粒子修饰石墨烯复合材料。以石墨烯和醋酸盐为原料,均匀混合后采用分段加热的方法成功制备出石墨烯负载银、钴、镍纳米粒子复合材料,该方法没有污染而且可以大量生产。实验中考察了金属负载量对制备的复合材料的影响,并采用扫描电镜和X-射线衍射2种方法对制备的复合材料进行了表征。结果表明：银、钴及镍纳米粒子可以均匀地负载在石墨烯表面;负载的银、钴及镍纳米粒子粒度分布范围窄,而且结晶度好。制备的复合材料有望在热管理领域及催化领域发挥其优势。

英文摘要：

Dry method is used to prepare metal nanoparticle-decorated graphene composite in order to avoid hard pollution on envi- ronment and being not mass production resulting from wet preparation. Ag, Co, and Ni nanoparticles-decorated graphene composite is prepared by uniformly mixing graphene and acetates followed by segmented heating method. No pollution on environment in the process and the composite can be mass produced. The effect of metal loading on the composite is studied. Scanning electric microscope and X-ray diffraction are applied to characterize the obtained composite. The results show that the metal nanoparticles with narrow diameter distribution decorate uniformly on the graphene surfaces. All the metal nanoparticles crystallize well. It is hopeful that the obtained composite can be applied well in the region of thermal management and catalyzation.
