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......
of a dense titania film with a Ni-free zone near its top surface. In comparison, Ni can still be detected on the outer NiTi surface by the conventional AOP using the UV/H2O2 system. The depth profiles of O, Ni, Ti show that the film possesses a smooth graded interface structure next to the NiTi substrate and this structure enhances the mechanical stability of titania film. The titania film can dramatically......
with nanotubes can be applied to forming film-coating or titania particles on nanotube surfaces. As they did not mention the difference between the photocatalytic features of these composites... composite indicated that TEOT as titania precursor coated the MWCNT surface with a thin film, whereas TTIP produced titania particles on the MWCNT surface. Accordingly, it might be the root cause......
of roasting high-titanium slag with concentrated sulfuric acid was proposed to prepare titanium dioxide, and the roasting kinetics of titania was studied on the basis of roasting process. The effects... sulfuric acid; titania 1 Introduction Titanium dioxide is an important inorganic chemical material, and is extensively used in white pigment, paper, plastics, rubbers, porcelain, and fibers, etc [1-4......
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......
vapor is adsorbed to form a film on both internal and external surfaces of ACFs, and hydrolyzed with adsorbed water, the fiber surface will be deposited with a titania layer. According... Interposition fixing structure of TiO2 film deposited on activated carbon fibers FU Ping-feng(傅平丰)1, LUAN Yong(栾 勇)2, DAI Xue-gang(戴学刚)2 1. Research Institute of Indoor Environment, Beijing......
Structure and property of mesoporous molybdenum/carbon co-doped brookite titania L? Xiao-meng(吕晓萌)1, LIU Jun(刘 军)2, ZHANG Hui(张 辉)1, DING Jian-lin(丁建林)1, XIE Ji-min(谢吉民)1 1. School of Chemistry... brookite TiO2. Key words: co-doping; brookite titania; photocatalysis  ......
September 2011 Abstract: Titania films with nano-sized pores were prepared on the NaOH-HCl pretreated NiTi alloy substrate by sol-gel method. A crack-free film is obtained for the sample with a dense inner.... The X-ray photoelectron spectroscopy results indicate that the titania film completely covered the NiTi substrate for sample TC1+1. The sample TC1+1 is hydrophilic with a contact angle about 20°, and UV......
Synthesis of rutile from high titania slag by pyrometallurgical route ZHANG Li1, LI Guang-qiang2, ZHANG Wu1 1. School of Materials and Metallurgy, Northeastern University, Shenyang 110004, China... for the conversion of high titania slag, containing 70%-75% TiO2 and with MgO, FeO, CaO, Al2O3 and SiO2 as main impurities, into a synthetic rutile, 90%-95% TiO2, which satisfies the requirements......
Trans. Nonferrous Met. Soc. China 23(2013) 3306-3311 Preparation of TiO2/ITO film by liquid phase deposition and its photoelectrocatalytic activity for degradation of 4-aminoantipyrine Dan LI, Hai... and Technology, Changsha 410004, China Received 12 October 2012; accepted 11 April 2013 Abstract: A thin layer of TiO2 film was deposited on ITO surface via the liquid phase deposition (LPD) process......
