摘要
The present invention relates to a method for preparing a porous graphene oxide for hydrogen storage and a porous graphene oxide for hydrogen storage prepared thereby, and specifically, a graphite oxide powder using a modified Hummers method from graphite powder. Synthesizing; And it relates to a porous graphene oxide manufacturing method comprising the step of heat-treating the graphite oxide powder at a temperature of 200 ~ 800 ℃ and a porous graphene oxide for hydrogen storage prepared by the method. In the porous graphene oxide prepared according to the present invention, oxygen functional groups such as hydroxyl and carboxyl groups present in graphite oxide are reduced during the heat treatment process, and interlayer pores expand from micro to mesoporous regions when exiting from the graphite oxide layers, This has an advantageous structure not only for storing hydrogen, but also for use as an adsorbent for adsorbing harmful gases or specific gases, as well as capacitors, batteries that require a conductive porous body.
