摘　　要：利用层间插入反应,合成HNdNb2O7/(Pt,TiO2)层状光催化纳米复合材料.采用X射线衍射、紫外-可见光漫反射、比表面积测定分析等分析手段对所制备的材料进行了表征.通过光照分解水,考察了所制备的材料的光催化性能,结果表明所制备的HNdNb2O7/(Pt,TiO2)纳米复合材料具有较高的光催化分解水效率并且其光催化活性稳定.HNdNb2O7 / (Pt , TiO2 ) was fabricated by successive intercalation reactions. The samples were identified by X-ray diffraction, UV-3100 ultraviolet-visible(UV-Vis) spectrophotometer, surface area analysis etc. The photocatalytic activities of the prepared layered nanocomposites were investigated by water splitting with UV-light irradiation. The result indicates that HNdNb2O7 / (Pt , TiO2 ) has not only excellent photocatalytic activities, but also its photocatalytic activities are stable.
