摘要

二氧化钛存在下的光催化过程为破坏有害有机污染物提供了一条有趣的途径,它在UV-A域中运行,并有可能利用太阳辐射。在合成的纳米TIO2上研究了太阳能光催化降解造纸废水。用x射线衍射(XRD)等技术对催化剂进行了表征,合成的催化剂的光催化活性增强归功于结晶度,纳米尺寸,大量的表面羟基物质和减小的带隙。

Treatment of highly polluted paper mill waste water by solar photocatalytic oxidation with synthesized nano Tio2
Photo catalytic processes in the presence of titanium dioxide provide an interesting route to destroy hazardous organic contaminants, being operational in the UV-A domain with a potential use of solar radiation. The solar photo catalytic degradation of paper mill wastewater has been studied over synthesized nano TIO2. The catalyst was characterized by techniques like x-ray diffraction (XRD)‥ The enhanced photo catalytic activity of the synthesized catalyst is attributed to the crystalinity, nano size, large amount of surface hydroxyl species and reduced band-gap.
