Zusammenfassung:	The present invention provides an ion catalyst for odor removal and a manufacturing method, and more specifically, the ion catalyst stably and high-efficiently removes odor discharged from a semiconductor sewage and wastewater treatment plant and during a semiconductor process. According to the present invention, the method for manufacturing the ion catalyst comprises: a step (a) of mixing a porous support with nano-silica sol to form a nano-silica thin film on surface of the porous support; a step (b) of mixing Al(OH)_3 aqueous solution with the porous support, on which the nano-silica thin film is formed, to introduce a middle connector catalyst; a step (c) of mixing the porous support, into which the middle connector catalyst is introduced, with an aqueous solution containing a first transition metal and a second transition metal precursor to form a catalyst composite; and a step (d) of heat-treating the catalyst composite at 220-350°C and cooling the same to manufacture the ion catalyst, wherein the ion catalyst of the step (d) has nano-silica-aluminum (Al)-first transition metal-second transition metal. 본 발명은 반도체 오·폐수처리장과 반도체 공정 중에 배출되는 악취를 안정적 및 고효율로 제거하는 악취 제거용 이온 촉매 및 그 제조 방법에 대하여 개시한다. 본 발명에 따른 이온 촉매 및 그 제조 방법은 (a) 다공성 지지체와 나노실리카 졸을 혼합하여, 상기 다공성 지지체 표면에 나노실리카 박막을 형성하는 단계; (b) 상기 나노실리카 박막이 형성된 다공성 지지체와 Al(OH)수용액을 혼합하여 중간연결자 촉매를 도입하는 단계; (c) 상기 중간연결자 촉매가 도입된 다공성 지지체와 제1전이금속과 제2전이금속 전구체를 포함하는 수용액을 혼합하여 촉매 결합체를 형성하는 단계; 및 (d) 상기 촉매 결합체를 220~350℃에서 열처리한 후 냉각하여 이온 촉매를 제조하는 단계;를 포함하고, 상기 (d) 단계의 이온 촉매에는 나노실리카-알루미늄(Al)-제1전이금속-제2전이금속이 형성되는 것을 특징으로 한다.
