Disclosed is a method for manufacturing a photocatalytic filter for air purification. The present manufacturing method comprises the steps of: oxidizing a titanium metal to obtain a nanostructured titanium dioxide (TiO2); adding the nanostructured titanium dioxide to an acidic fluorine-containing solution to allow a reaction to occur therebetween for a predetermined period of time; and, after treatment in the acidic fluorine-containing solution, performing heat treatment on the nanostructured titanium dioxide. L'invention concerne un procédé de fabrication d'un filtre photocatalytique pour purifier l'air. Ledit procédé de fabrication comprend les étapes consistant à : oxyder un métal de titane pour obtenir un dioxyde de titane nanostructuré (TiO2) ; ajouter le dioxyde de titane nanostructuré à une solution contenant du fluor acide pour qu'une réaction se produisent entre ceux-ci pendant une durée prédéterminée ; et, après traitement dans la solution contenant du fluor acide, soumettre le dioxyde de titane nanostructuré à un traitement thermique. 공기 청정용 광촉매 필터의 제조 방법이 개시된다. 본 제조 방법은, 티타늄 금속을 산화시켜 나노 구조의 이산화티타늄(TiO2)를 획득하는 단계, 나노 구조의 이산화티타늄을 산성의 불소 함유 용액에 넣어 기 설정된 시간동안 반응시키는 단계 및 산성의 불소 함유 용액에서의 처리 이후, 나노 구조의 이산화티타늄에 열처리를 수행하는 단계를 포함한다.
