초록
본 연구에서는 다이에틸렌글리콜 용매 상에서 공침법을 이용하여 기공성 아연 구형 산화물과 구리-아연 복합 산화물을 합성하였다. 합성된 물질들의 물리화학적 특성은 전자현미경, X-선 회절분석, N2 흡착, H2-TPR 방법을 통하여 분석되었고, 다양한 Cu 함량(0, 6.6, 21.3 36.4, 54.6, 77.8 wt%)을 포함한 Cu-ZnO 복합 산화물을 고정층 반응 장치에서 일산화탄소 산화 반응성을 고찰하였다. 합성된 산화물 중에서 Cu 함량이 증가할수록 Cu-ZnO의 비표면적과 미세 기공 부피는 감소하였으며, Cu (36.4 wt%)-ZnO이 가장 좋은 일산화탄소 산화 반응성을 나타내었다.
In this study, porous ZnO sphere and Cu-ZnO composite were synthesized by coprecipitation method in diethylene glycol solvent. The physicochemical properties of as-prepared composite materials were characterized by SEM, XRD, N2-sorption and H2-TPR. A series of porous Cu-ZnO with different Cu contents (0, 6.6, 21.3, 36.4, 54.6, 77.8 wt%) was investigated for CO oxidation activity in a fixed bed reactor system. With increasing Cu content in Cu-ZnO the surface area and micropore volume of Cu-ZnO are decreased and Cu (36.4 wt%)-ZnO shows higher activity for CO oxidation compared to the others.
