Zusammenfassung:	The present invention relates to a method of preparing a titania carrier used for a nitrogen oxide removal catalyst, comprising the steps of: using titanium tetraisopropoxide (TTIP) as a starting material to form a pillaring solution; dispersing pillared interlayer clay (PILC) in water to form a suspension; and obtaining the titania carrier (Ti-PILC) from a mixture solution of the pillaring solution and the suspension. Accordingly, the present invention serves to simplify the production process of the titania carrier, and eliminate sources of hydrochloric acid generation during the production process, thereby minimizing environmental pollution. Further, the present invention can improve the pore size distribution and specific surface area properties of the catalyst to achieve far superior denitrification catalyst capacity. 질소산화물 제거 촉매에 사용되는 티타니아 담체의 제조 방법은 테트라이소프로폭사이드 티타늄(titanium tetraisopropoxide, TTIP)을 출발 물질로 사용하여 필러링 용액을 제조하는 단계; PILC(pillared interlayer clay)를 물에 분산시켜 현탁액을 제조하는 단계; 및 필러링 용액 및 현탁액의 혼합 용액으로부터 티타니아 담체(Ti-PILC)의 분말을 얻는 단계를 포함한다. 이에 따라, 티타니아 담체의 제조 공정을 간소화하고 제조 공정중에 염산 발생 요인을 없애 환경 오염을 최소화할 수 있으며 기공 분포도 및 촉매 비표면적 특성을 향상시켜 보다 우수한 탈질 촉매능을 구현할 수 있다.
