| 제목 | Synthesis and Properties of Highly Ordered Mesoporous Materials with Spinel Structure |
| 초록 | Mixed Oxides with spinel structure have received great attention for decades in the field of electrolytes, refractories, and catalytic material due to their optical, electrical, and catalytic properties. Highly ordered mesoporous AB2O4 (A=Mn, Co, Ni, and Zn, B=Mn, Fe, Co) spinel materials have been synthesized through nanocasting method, using KIT-6 silica as a hard template. From low-angle X-ray diffraction (XRD) patterns of highly ordered mesoporous of AB2O4 (A=Mn, Co, Ni, and Zn, B=Mn, Fe, Co) spinel materials, a new (110) peak was observed before 2θ=1°. It indicates the meso-structure transformation from cubic to tetragonal or the lower space group after the silica template etching process. N2 adsorption-desorption isotherms exhibit the obtained replicas have high specific surface areas (92–125 m2/g), and large pore volumes (0.11–0.26 cm3/g). |
