摘　　要：以片状高岭石为基材,采用Fe3+化合和Fe2O3直接热合两种掺杂方法制备铁掺杂高岭石基纳米TiO2光催化材料。应用结果表明,两种掺杂方式均不同程度地提高了材料的光催化活性,且在自然光下的催化效果也有明显提高。该研究对矿物负载型光催化材料在自然光下降解有机物、抗菌、净化空气的工业应用具有重要意义。Photocatalytic material was prepared by means of two doping methods, namely Fe^3 ＋ chemical synthesis and Fe2O3 direct heating synthesis with TiO2 as substrate. The application of the prepared material indicated that both the doping methods raised the photocatalytic activity of the material in different ways and obviously improved the catalytic effect in the sunlight. This research is of important significance to the industrial application of mineral-loading type photocatalytic materials in organic degradation, antibacterial and air purification under the sunlight.
