▎ 摘　　要

NOVELTY - The air purifier (100) has a graphene ceramic filter (130) that removes fine dust from the air introduced into a case passing through an air inlet (111) as an air intake fan operates. A graphene membrane hybrid filter (140) captures and separates carbon dioxide from air as the air from which fine dust is removed by the graphene ceramic filters passes through. The ceramic filter is hydrolyzed by putting 3-glycidyloxyproply trimethoxysilane (GPTMS) and silane coupling agent in an aqueous ethanol solution, and stirring together with graphene oxide to modify the surface of the graphene oxide. USE - Air purifier for removing fine dust and carbon dioxide. ADVANTAGE - The air purifier removes fine dust and carbon dioxide from indoor air without installing a separate air circulator, thus significantly reducing equipment costs for improving indoor air quality, and reducing indoor cooling and heating costs. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the air purifier for removing fine dust and carbon dioxide (Drawing includes non-English language text). 100Air Purifier 111Air inlet 120Air Inlet Fan 130Graphene Ceramic Filter 140Graphene membrane hybrid filter
