Eu2+/Gd3+-codoped nanocrystalline titania catalyst and its photocatalytic activity under natural light ZHOU Yi(周 艺)1, 2, HUANG Ke-long(黄可龙)1, ZHU Zhi-ping(朱志平)1, 2, XIA Chang-bin(夏畅斌)1 1. School... 410076, China Received 15 July 2007; accepted 10 September 2007 Abstract: Eu2+/Gd3+-codoped nanocrystalline titania catalysts were prepared by a modified sol-gel method. Powder X-ray diffraction......
Preparation and thermal decomposition mechanism of Mg,Al-hydrotalcite nano-crystals with titania doping REN Qing-li(任庆利)1, LUO Qiang(罗 强)2 1.School of Technical Physics, Xidian University, Xi... with titania doping was synthesized by one-step liquid reaction method at atmospheric pressure. The preparation of the Mg,Al-hydrotalcite nano-crystal after doping titania was investigated according......
Regularity control of porous anodic alumina and photodegradation activity of highly ordered titania nanostructures LIU Xiang-zhi(刘祥志), XU Ming-xia(徐明霞), TIAN Yu-ming(田玉明),SHANG Meng(尚 萌), ZHANG... with the sol-electrophoresis deposition and sol-gel method respectively to prepare highly ordered titania nanostructures. The diameter and length of the obtained nanostructures were determined......
Selective enrichment of TiO2 and precipitation behavior of perovskite phase in titania bearing slag WANG Ming-yu(王明玉)1, ZHANG Lin-nan(张林楠)2, ZHANG Li(张 力)2, SUI Zhi-tong(隋智通)2, TU Gan-feng(涂赣峰)2... scale test were studied. The results show that the increase of steel slag does good to titania enrichment, however, it isn’t useful for the growth and coarsening of the perovskite phase. The additive Si......
