WebThe present work investigated hydrothermal synthesis of titanium/hydroxyapatite (Ti/HA) nanocomposite at varied Ti content. The synthesis was performed by coprecipitation method using CaO, ammonium dihydrogen phosphate and titanium oxide chloride precursor with the additional cetyl trimethyl ammonium chloride as templating agent, followed by … http://cje.ustb.edu.cn/cn/article/doi/10.13374/j.issn1001-053x.2003.04.014
WebSynthesis of n-butyl lactate with TiSiW12O40/TiO2 as catalyst has been studied. The effect of factors on the yield is discussed. The optimized conditions are: the molar ratio of n-butyl alcohol to lactic acid 1.1:1; the amount of TiSiW12O40/TiO2 is 5%(wt) of lactic acid; the reaction time 1.5 hour and the conversion rate of lactic acid is 98.2%. http://snst-hu.lzu.edu.cn/zhangyi/ndata/Keggin_structure.html
Web由于杂多酸比表面积较小，在实际应用中，要将其负载在适当的载体上以提高其比表面积，常用的催化载体包括活性炭、膨润土、SiO2、r-Al2O3、TiO2和 MCM-41分子筛等，近年来也有人用炭化树脂、活性炭纤维、炭纳米管、麦饭石、蒙脱土和多孔玻璃微珠等作载体。 WebIt was demonstrated that TiSiW12O40/TiO2is an excellent catalyst. Various factors concemed with esterifica-tion were investigated. The optimum conditions were found: the mole ratio of alcohol to acid is 1.3:1, the mass ratio ofcatalyst to reactants is 1.5%, and the reaction time is 1.0 h.
WebThe photocatalytic degradation of methyl violet using TiSiW12O40/TiO2 as a novel eco-friendly catalyst under simulated natural light irradiation was investigated. The physical characterizations were carried out by TG/DTA, FT-IR, XRD, and UV-visible spectra. The effects of the initial methyl violet concentration, the solution pH, and catalyst dosage on …
WebIt showed that the solid super acid TiSiW12O40/TiO2 was an excellent catalyst, the yield of the ethyl acetate could reach over 69.38% under molar ratio of ethyl alcohol and acetic acid 1.3:1, the reaction temperature of 84~90℃, reaction time of 1.0 h and amount of TiSiW12O40/TiO2 solid super acid catalyst of 1.0%. does antibacterial soap help acneWebDeWalt / Delta Porter-Cable Factory Service #042. 3557-B WILKINSON Charlotte, NC 28208 USA.
