石墨烯负载多酸化合物的制备研究

Research on the Preparation of Graphene Loaded Polyoxometallate

制备了氧化石墨(GO),并以此为载体,利用光催化反应制备了POM/GO复合材料,达到分散氧化石墨烯的目的,避免氧化石墨烯的重新石墨化,为氧化石墨烯有效负载多酸化合物的研究提供了新的思路.以氧化石墨为基础,依据不同负载前躯体的特性,分别制备了不同多酸化合物负载的石墨烯-H3PW12O40、石墨烯-H3PMo12O42材料.采用X射线粉末衍射、透射电镜等多种现代化测试仪器和方法对样品进行了结构和形貌表征.

Graphite oxide was prepared in this paper, and as the carrier, the use of photocatalytic reaction composite material was prepared, achieve the purpose of dispersed graphene oxide was achieved, graphene oxide of graphitization was avioded, the payload for graphene oxide acid compounds of study provides a new train of thought. On the basis of graphite oxide, according to the features of different load before body respectively, the preparation of the different load more acid compounds of -H3PW12O40 graphene materials, -H3PMo12O42 graphene materials. The structure and morphology of the sample were characterized by X - ray powder diffraction, transmission electron microscopy （sem） and other modern testing instruments and methods.
