▎ 摘　　要

NOVELTY - A composite porous material has porous structure having pore size of 100 nm to 5 mu m interconnected with matrix structure having scale size of 100 nm to 5 mu m forming homogeneous three-dimensional mesh structure. The matrix structure comprises titanium dioxide dispersed in graphene sheet as continuous phase. The matrix structure comprises 0.5-20 %mass graphene, 50-70 %mass titanium dioxide and remainder of carbon. USE - Composite porous material is used for photocatalyst, lithium battery and supercapacitor (all claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of composite porous material, which involves using polymer micelle solution containing styrene block copolymer, solvent, graphene oxide, precipitating agent and titanium dioxide.
