Title: Mesoporous gallium oxide structurally stabilized by yttrium oxide

Abstract

Since the synthesis of mesoporous silicas such as MCM-41 and FSM-16 with large internal surface areas and uniform pore sizes, the surfactant templating method has been used to synthesize mesoporous metal oxides, including titanium, aluminum, niobium, and tantalum oxides. The mesostructured metal oxides are taken to be useful not only as catalysts and separating or adsorbing agents but also as functional host materials with optically, electrically, or magnetically unique properties, owing to the shape-specific and/or quantum effects of their thin inorganic skeletons. Mesoporous zirconium oxide and phosphate and hafnium oxide are promising as acid catalysts. Layered and hexagonal mesostructured titanium oxides, for example, were observed to be photocatalytically active. Aluminum and gallium oxides with a mesoporous structure are also expected to serve as a catalytic of other functional material. In this paper, the authors report the synthesis and characterization of mesoporous gallium oxide stabilized by yttrium oxide.
