The present invention relates to an air purifier using a nano-metal / photocatalyst sol to respond to the LED lamp, The air containing the impurity is introduced, and impurities adsorbed by the adsorbent, the impurities adsorbed in the air purifying device that is decomposed by the optically active nano-metal / photocatalytic coating layer coated on the surface of the adsorbent, the LED light source to cause the optically active ( LED) lamp, and the nano-metal / photocatalytic coating is, the alcohol-based organic solvent and 10 to 30 parts by weight, and 50 to 70 parts by weight of water as a water-based solvent, 5 to 15 parts by weight of the titanium precursor and a transition metal as the metal precursor 0.5 ~ and 10 parts by weight of nitric acid as a catalyst in a mixture of 0.5 to 5 parts by weight of stabilizer of 0.1 to 5 parts by weight of a chelating reactor, 60 ~ at a temperature of 90 formed by stirring Sikkim nano-metal / photocatalytic slurry composition, characterized in that The air purification device using nano-metal / photocatalyst sol to respond to an LED lamp with a technical base. Accordingly, the present invention according to the above configuration is 395 ~ 400 LED (LED) is optically active in response to a lamp employing a nano-metal / photocatalyst sol is coated filter to decompose the pollutant adsorbed on the adsorbent is saturated, so the wavelength filter This increased efficiency has the advantage that the removal efficiency increased.본 발명은 엘이디 램프에 반응하는 나노금속/광촉매 졸을 이용한 공기정화장치에 관한 것으로, 불순물이 포함된 공기가 유입되어 불순물이 흡착제에 흡착되고, 흡착된 불순물은 흡착제의 표면에 코팅된 나노금속/광촉매 코팅층의 광활성에 의해 분해되는 공기정화장치에 있어서, 상기 광활성을 일으키는 광원은 엘이디(LED)램프이고, 상기 나노금속/광촉매 코팅층은, 알콜계 유기용제 10~30 중량부와, 수성용매로서 물 50~70 중량부와, 티타늄 전구체 5~15 중량부와, 금속 전구체로서는 전이금속 0.5~10 중량부와, 촉매로서 질산 0.5~5 중량부 및 킬레이트 안정제 0.1~5 중량부를 반응기에서 혼합하고, 60℃~90℃의 온도에서 교반시킴에 의해 형성된 나노금속/광촉매 슬러리 조성물임을 특징으로 하는 엘이디 램프에 반응하는 나노금속/광촉매 졸을 이용한 공기정화장치를 기술적 요지로 한다. 이에 따라, 상기의 구성에 의한 본 발명은 395~400㎚ 파장대의 엘이디(LED) 램프에 반응하여 광활성되어 오염물질을
