摘要：

With　zirconium　n-propoxide　as　Zr　source　and　triethanolamine　as　template,　a　mesoporous　zirconia　was　synthesized　via　hydrothermal　route.　By　means　of　XRD,　TEM　and　N2　adsorption-desorption　analysis,　the　related　mechanism　was　investigated.　The　results　showed　that　by　the　chelation　with　triethanolamine,　zirconium　n-propoxide　transformed　into　a　complex,　its　hydrolysis　and　condensation　rates　could　be　controlled　during　the　sol-gel　process,　and　then,　the　particles　condensed　into　well-arranged　pore　walls　via　self-assembly　route,　and　the　crystallization　could　be　controlled　to　finally　form　the　mesoporous　materials.
