▎ 摘　　要

NOVELTY - The purifier (120) has a fan for introducing contaminated air containing viruses and bacteria. An air purifying unit removes the viruses and bacteria. A control unit controls the fan and the air purifying unit. A power supply unit supplies power, where the air purifier passes through a photochemical reaction nano-composite catalyst filter (121) that sterilizes while contacting viruses and bacteria. A UV lamp (122) irradiates UV rays and the photochemical reaction nano composite catalyst filter. The UV lamp includes an ozone removal catalyst filter that removes ozone, a by-product remaining in the air, and the photochemical reaction nano composite catalyst material, which is a mixture of nickel nitrate and graphene so that oxidation and reduction reactions in UV and visible light are activated. USE - Air purifier for sterilizing air contaminated with viruses and bacteria using photochemical reaction nano composite catalyst filter. ADVANTAGE - The air purifier prevents diseases and leads healthy life by supplying fresh air by removing air contaminated with viruses and bacteria using the photochemical reaction nanocomposite catalytic filter. DESCRIPTION OF DRAWING(S) - The drawing shows an exploded perspective view of an air purifier. 10Case 11Fixed frame 120Air purifier 121Photochemical reaction nano-composite catalyst filter 122UV lamp
