| 摘 要： | 高温固相法制备层状钛铌酸钾盐（K T iN bO5）。通过硝酸酸化、剥片处理等获得亚级钛铌酸钾纳米片。分别用二氧化钛和氢氧化铁溶胶对钛铌酸钾纳米片进行复合，获得两种钛铌酸钾纳米片为基质的复合纳米催化剂。最终分别考察了亚甲基蓝（M B ）在两种改性的钛铌酸钾纳米片表面上吸附和光催化效果。结果表明，两种钛铌酸钾纳米片为基质的复合材料在氙灯下对亚甲基蓝均具有良好地复合改性的光催化降解效果。

| Abstract: | The layered potassium titanoniobate （KTiNbO5 ） was synthesized by the high temperature solid state method . Furthermore ,the nanosheet consist of titanoniobate acid could be obtained through ions exchanging and exfoliation . Two nanoparticles （Fe（OH）3 and TiO2 ） were loaded onto the surface of titanoniobate acid nanosheets by the electrostatic attraction , respectively .In the end ,these two kinds of composites were applied in photocatalytic methylene blue （MB） under the irradiation of Xe light .The result indicated that these two kinds of composites have better photocatalytic effect than the single titanoniobaten nanosheets . |
