▎ 摘　　要

NOVELTY - The gas absorbing bag has a ventilating shell and an absorbing material that is embedded in the shell, where the absorbing material is a porous frame with three-dimensional graphene porous particles (1), and nano particles (2) are filled in the pore space of the 3D graphene porous particle. USE - Gas adsorption bag for household air purifying and sterilizing dust, microorganism, smoke, pollen and pet hair. ADVANTAGE - The gas adsorption bag of graphene composite structure has high specific surface area as porous frame, and high adsorbability and functionality, thus improving the service life and reducing the use cost of the gas adsorbent bag. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic structural view of the absorbent particles. Three-dimensional graphene porous particles (1) Nano particles (2)
