【摘要】 半导体光催化氧化技术作为一种水处理方法在环境保护方面具有突出的优点和很强的潜在应用价值,半导体光催化氧化技术被广泛用于水体中有机污染物的降解[1,2],采用可溶性淀粉为碳源和硫酸氧钛为钛源,通过二次水热合成方法制备了C-TiO2核-壳型复合材料。通过XRD、SEM和TEM对所制备的C-TiO2核-壳型复合材料进行了表征。以甲基橙为模拟污染物,通过在模拟太阳光下对所制备C-TiO2核-壳型复合材料的光催化性能进行了评价,结果表明,30 min内即可将溶液里的甲基橙完全降解,因此,该复合材料具有良好的光催化性能,在降解废水中的有机物方面具有潜在的应用价值。更多还原

【Abstract】 Use of starch as a carbon source and titanyl sulfate as a titanium source, C-TiO2 composites with coreshell structure were prepared by hydrothermal synthesis process. The as-prepared C-TiO2 composites were characterized by X-ray diffraction(XRD), scanning electron microscopy(SEM) and transmission electron microscope(TEM). In addition, use methyl orange as simulated contaminants, the photo-catalytic performance of the C-TiO2 composites were evaluated. The results show that the methyl orange(MO) solution could be completely degraded within 30 min under simulated sunlight irradiation. The composite material has a promisingly application in degradation of organic compounds from the wastewater.更多还原
