Abstract
상기와 같은 본 발명에 따르면, 이산화티타늄 나노분말에 이종의 전이금속을 담지시키고 소성과정을 통해 이종 전이금속 및 이산화티타늄의 산화물나노복합체를 제조함으로써, 종래 이산화티타늄보다 새롭게 발현되는 에너지 준위로 인한 낮은 밴드갭을 갖고 가시광선 영역에서의 광활성, 높은 광촉매 효율을 나타내며 종래 한 가지의 전이금속으로 도핑된 이산화티타늄에 비하여 정공-전자쌍의 재결합률이 감소되어 수용액 상의 오염물 처리에 있어 높은 광분해능을 나타내는 효과가 있다.
Description
도 2는 이종 전이금속과 TiO2의 복합화를 통해 제조된 새로운 산화물나노복합체의 광 조사시간에 따른 메틸렌블루 분해 곡선.
