Cerium oxide-doped TiO_2 was prepared by the combined method of carbon black adsorption and sol-gel method.Carbon black was used to adsorb sol produced by hydrolysis of butyl titanate in the experiments.CeO_2/TiO_2 nano powder was formed by gelation at room temperature,drying,grinding,and burning of the above composite.The prepared powder had high purity and even crystal structure,and the average particle size was about 14 nm.The comparison experiment of light degradation of xylenol orange,catalytic perform...

Ti O2作为一种具有强氧化性的高效、节能光催化材料,近年来受到了国内外研究者的广泛关注。但是,Ti O2材料的光响应范围相对较窄、作为催化剂使用过程中容易流失以及使用结束后回收难等问题严重影响其实际应用。研究发现,在Ti O2中掺杂某些微量的元素对其进行改性,能有效提高Ti
