Abstract
수열합성법을 이용하여 zinc acetate와 암모니아수를 80 ℃의 고온에서 침전 반응시켜 광촉매용 산화아연 입자를 제조하였다. 암모니아수의 pH, 전구체인 zinc acetate의 농도 변화가 산화아연 입자의 특성에 미치는 영향을 조사하였다. 암모니아수 pH 11, zinc acetate의 농도 1.0M, 침전반응온도 80 ℃의 조건에서 제조된 산화아연이 평균 입경 3 μm로 가장 작았으며, SEM과 XRD 분석을 통하여 육방정계의 봉상 막대형, Anatase 형태의 산화아연이 제조됨을 확인할 수 있었다. DRS와 PL 분석을 통하여 제조된 산화아연이 200~400 nm의 자외선 영역에서 활성을 나타냄을 확인하였고, 자외선 조사 하에서 광분해 실험을 수행한 결과 산화아연은 3시간 동안 식용색소인 Brilliant blue FCF를 57%까지 분해할 수 있었다.
Photocatalytic zinc oxide powders were prepared from precursor zinc acetate and ammonia solution at elevated temperature, 80 ℃, by hydrothermal precipitation method. The effect of operating parameters, pH of ammonia solution and concentration of zinc acetate solution, on the characteristics of zinc oxide powders were experimentally examined. Zinc oxide powders prepared at the conditions of pH 11, zinc acetate concentration of 1.0 M, precipitation temperature of 80 ℃, showed smallest average particle diameter of 3 μm. SEM and XRD analysis confirmed that prepared zinc oxide has hexagonal rods structure, and Anatase type crystallinity. In addition, DRS and PL analysis showed that the zinc oxide has activity at the range of 200~400 nm of UV light. And the zinc oxide decomposed 57% of a foodcolor stamp Brilliant blue FCF for 3 hours under the UV radiation.
