▎ 摘　　要

NOVELTY - A graphene channel purified granule comprises a catalytic core and outer layer, where the outer layer is covered on the outer surface of the catalytic core, the outer layer comprises multiple pores and the graphene channel, the a catalytic core is connected through the graphene channel and the surface of the pore, and the catalytic core is a sphere made of potassium permanganate and/or manganese dioxide. USE - Graphene channel purified granule. ADVANTAGE - The graphene channel purified granule can be prepared with effectively saving space of pores and channels, capturing a harmful component absorbed in the air, and better processing effect, and not cause secondary pollution. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing graphene channel purified granule.
