【摘要】 用自制的纳米ZnO在室外阴天、太阳光照射、室内紫外灯照射等条件下对不同有机染料的降解性能作了系统的研究。结果表明纳米ZnO在太阳光照射条件下对弱碱性有机染料溶液的降解效果较好。本文还比较了自制纳米ZnO与纳米TiO2对有机染料的降解性能,结果表明ZnO的降解效果优于TiO2。更多还原

【Abstract】 Degradation characteristics of different organic dyes were studied systematically in the presence of nano zinc oxide under various conditions including cloudy sky outside,sunshining and ultraviolet lighting indoor.The results indicated that the best degradation effet or alkalescent organic dyes was obtained in the presence of nano zinc oxide under sunshining.Furthermore,the degradation characteristics of organic dyes were compared in the presence of nano zinc oxide and nano titanium dioxide,it was found that the degradation effects for nano zinc oxide were better that those for nano titanium dioxide..更多还原
