中文摘要：
以固相反应合成了LiAlNb2O7，并用离子交换法制备出LiAlNb2O7，通过紫外光分解等反应将Pt和TiO2分别掺杂到HAlNb2O7上。运用X射线衍射、漫反射、ICP和比表面积等测试技术对样品进行表征。在波长大于290nm的100w汞灯照射30min下，1．0g样品可催化分解甲醇溶液（10％）产生氢气约7mL，表明所制备的材料具有较高的光催化活性。
英文摘要：
HAlNb2O7 was prepared by calcining stoiehiometrie mixture of Li2CO3, Al2O3 and Nb2O5, followed by ion exchange with HCl. HAlNb2O7/M （M = Pt, TiO2）composite photocatalyst was synthesized by successive reaction of HAlNb2O7 with [Pt（NH3）4]Cl2 and C12H28O4Ti respectively under UV light irradiation. Then, the XRD, DRS（ diffuse reflectance spectrum）, ICP （Inductively Coupled Plasma）, and specific surface area measurements were made on the samples. Under irradiation with λ 〉 290 nm from a Hg lamp of 100 W for 30 min, about 7 mL hydrogen was produced form 1250 mL methanol solution （10%） containing lg of dispersed HAlNb2O7/Pt.
