Synthesis and Characterization of Ru/Al2O3 Nanocatalyst for Ammonia Synthesis
Ru/Al2O3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of RuCl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. The samples were characterized by TEM, XRD and TPR techniques. The catalytic performance tests were carried out in a fixed-bed micro-reactor under diffe...

ru/al2o3 catalysts were prepared by conventional incipient wetness impregnation as well as colloid deposition of rucl3 precursor via in situ reduction with ethylene glycol (polyol) method on alumina support. the samples were characterized by tem, xrd and tpr techniques. the catalytic performance tests were carried out in a fixed-bed micro-reactor under different operating conditions. ethylene g...
متن کاملcomparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.
heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...
15 صفحه اولSynthesis, structural characterization and catalytic activity of TiO2/Al2O3 photo-composite
In recent years, the effects of heterogeneous catalysts for the oxidation of organic and inorganic pollutants in industrial wastewaters are spread. Traditionally, these reactions are usually carried out using suspensions of photo-catalysts such as TiO2. A chemical method including TiCl4, Al(NO3)3, ethanol amine, ethyl acetoacetate and aqueous ammonia were used for the fabrication of TiO2-Al2O3 ...
متن کاملOxidative dehydrogenation of propane over V2O5/MoO3/Al2O3 and V2O5/Cr2O3/Al2O3: structural characterization and catalytic function.
The structure and catalytic properties of binary dispersed oxide structures prepared by sequential deposition of VO(x) and MoO(x) or VO(x) and CrO(x) on Al(2)O(3) were examined using Raman and UV-visible spectroscopies, the dynamics of stoichiometric reduction in H(2), and the oxidative dehydrogenation of propane. VO(x) domains on Al(2)O(3) modified by an equivalent MoO(x) monolayer led to disp...
