Abstract
如何提高光量子利用率和光量子效率是目前光催化材料研究中的两个关键问题。为了解决铋系半导体光催化剂光生载流子容易复合及其光量子利用率较低的问题,本文采用简单易行的静电纺丝技术与软化学原位合成技术,设计制备一系列分布均匀、能级匹配的铋系纳米复合材料,并围绕这些材料在光催化领域内的应用性能开展研究。在可见光光催化剂的设计和材料的控制合成方面取得了一定的进展,为今后类似材料体系的构筑提供了参考依据,所合成材料具有良好的应用前景。 (1)采用静电纺丝法和溶液原位离子交换法成功合成了Bi2S3/Bi4Ti3O12核壳结构光催化剂,所构筑的纳米复合材料展现出比单一Bi4Ti3O12和Bi2S3更高的光催化...
 
To improve photon utilization efficiency and quantum efficiency is the focus of the photocatalytic materials research. In order to solve the problem of the rapid recombination of photo-generated carriers and the low utilization ratio of optical quantum of bismuth-containing semiconductor photocatalysts, in this work, a series of bismuth-containing nanocomposites with tightly interface, evenly dist...
