▎ 摘　　要

NOVELTY - Preparation of three-dimensional hierarchical porous graphene comprises adding graphite oxide to deionized water room temperature, ultrasonically stirring to obtain graphite oxide dispersion, adding metal polyoxometalate, ultrasonically mixing, slowly adding 10 wt.% polymer beads, ultrasonically mixing, filtering, drying, calcining under inert gas protective atmosphere, washing with hydrochloric acid, and drying. USE - Method for preparation of three-dimensional hierarchical porous graphene (claimed) used for supercapacitor, capacitive desalination and lithium ion batteries. ADVANTAGE - The graphene has unique three-dimensional hierarchical porous structure and excellent conduction characteristics. The method is simple and easy to control.
