摘要
通过化学氧化再还原的方法制备还原氧化石墨烯成为一种最可能大规模制备石墨烯的方法。但是该方法制备的石墨烯结构缺陷严重,同时含有氧官能团,其电子迁移率和导电率大大降低。B、N、S和O等异质原子是碳的邻近元素,异质原子对石墨烯的掺杂不仅可以改变石墨烯的结构,也可以从本质上提高石墨烯的电化学性能,所以,掺杂石墨烯引起了极大的研究兴趣。单一掺杂石墨烯具有优异的电催化活性,可以作为氧还原反应的催化剂。而研究发现,掺杂石墨烯复合材料可以具有多功能特性,在能源存储和转换以及环境污染物中具有广阔的前景。论文报道了几种掺杂石墨烯与无机材料和导电聚合物的杂化材料的软化学法制备、电化学性能以及在能源和环境中的应用。
The oxidation-post reduction method becomes the most possible approach for large-scale production of chemically reduced graphene. But graphene prepared by this method has serious structure disorder and remains oxygen-containing groups, which weaken its electrode transportation and conductivity. Heteroatoms like B, N, S and O are adjacent elements to carbon. The doping of such elements to graphene may change its structure and improve the electrochemical property of graphene. Therefore, doped graphene has attracted great interests~(1-2). Single doped graphene shows unique electrocatalytic activity and can be used as catalyst for oxygen oxidation reaction3. While it is found that, the hybrids of doped graphene show multi-function, and have a wide application prospect in energy storage and conversion and environmental detection. Herein, we report that the synthesis and electrochemical properties of several hybrids of doped graphene with inorganic materials and conducting polymers, and their application in energy and environment.
