摘要

本文采用原始的化学沉积方法制备了Ni和Co纳米团簇包覆的光催化TiO2微纳米粉末。通过磁强计测量磁化温度依赖性，研究了Ni和Co纳米团簇修饰TiO2晶粒的磁性能。他们的光谱学测量表明，Ni和Co涂层的TiO2纳米粉末的光吸收显著增加。利用电子顺磁共振波谱法研究了制备的磁性纳米粉体的光催化性能。

Photocatalytic and Magnetic Properties of TiO2 Micro- and Nano- Powders decorated by Magnetic Cocatalysts

In this paper, photocatalytic TiO2 micro- and nano-powders coated by Ni and Co nanoclusters were prepared by the original electroless deposition method. The magnetic properties of Ni and Co nanoclusters decorating TiO2 grains were studied by the magnetometry measurements of the temperature dependence of magnetization. Their optical spectroscopy measurements showed a significant increase in light absorption by Ni and Co coated TiO2 nanopowders. The photocatalytic properties of the obtained magnetic nanopowders were studied with Electron Paramagnetic Resonance spectroscopy as well.
