- 나노튜브형 TiO2미분말을 제조하여 분말의 비표면적을 향상시키는데 있어서,출발원료로 단가가 비싼 알콕사이드를 사용하는 대신 TiCl4를 사용하는 단계,광촉매 활성을 떨어뜨릴 수 있는 다른 금속 산화물이나 도펀트를 혼합하지 않고, TiCl4만을 사용 하는 단계,상기 단계 후 autoclave를 사용하는 대신 간단한 reflux 장치를 이용해 5M NaOH 수용액에 아나타제상 TiO2분말을 넣고 150℃에서 12시간 동안 온침 처리하므로서 나노튜브형 분말을 얻는 단계 온침온도를 조절하여 미세구조를 제어함으로서 분말의 비표면적을 향상시키는 단계로 이루어진 것을 특징으로 하는 TiO2분말 제조 방법
