研究了氧化石墨烯(GO)负载Co-Ni催化剂原位催化聚丙烯(PP)进行三维石墨烯碳纳米杂化材料的合成,同时考察材料作为超级电容器电极的电化学应用.将乙酸钴和乙酸镍按比例加入GO水溶液中,利用聚醚胺400(D-400)将二者还原为氢氧化物并自组装负载在GO表面,制备出GO负载Co-Ni催化剂(GO/Ni-Co).将GO/Ni-Co熔融共混到PP中,在氮气保护下裂解碳化共混得到石墨烯基碳纳米杂化材料.采用SEM、TEM、XRD和Raman等对其形貌结构进行表征.结果表明:利用该方法可成功制备一种三维石墨烯碳纳米杂化材料(RGO/C).将所制备的RGO/C应用于超级电容器,在扫描速率为2mV/s时,最大比电容达到595F/g,并且具有良好的循环稳定性.“,”In the presence of graphene oxide (GO)-supporting Co-Ni catalysts,a kind of graphene-based carbon nano hybrid materials was synthesized by catalytic cracking of polypropylene,and the electrochemical application of this material as a super capacitor was investigated.Firstly,the cobalt acetate and nickel acetate with a certain proportion were dispersed into GO aqueous solution,and then the polyetheramine-400 (D-400) was applied to reduce nickel acetate and cobalt acetate to hydroxides on the surface of GO layers,after that a kind of GO-supporting Co-Ni catalysts was prepared.The GO/Co-Ni catalyst was melt blended into polypropylene,and after the cracking carbonization,the graphene-based carbon nano hybrid materials were obtained (RGO/C).The SEM,TEM,XRD and Raman techniques were used to characterize the morphology and structure of RGO/C.The results demonstrated that a kind of RGO/C had been successfully synthesized via this method.At last,the RGO/C was used as the super capacitor.When the scan speed was 2mV/s,the maximum specific capacitance of RGO/C was 595F/g and it had good cycle stability.
