Ru nanoparticles stabilized by organosilane fragments: Influence of the initial Si/Ru ratio and thermal stability
The decomposition of the organometallic ruthenium precursor [Ru(COD)(COT)] (COD: 1,5-cyclooctadiene; COT: 1,3,5cyclooctatriene) in mild conditions (20 C, 3 bar H2) in n-pentane leads, in the presence of octylsilane (H3 SiC8H17) to the formation of stable Ru nanoparticles with narrow size distribution. The solids obtained after washing and drying were fully characterized by elemental analysis, T...
متن کاملRu nanoparticles stabilized by organosilanes: Influence of the initial Si/Ru ratio
Surface Organo-Metallic Chemistry on Metals (SOMC/M) [1] provides access to a new type of materials. The strategy is to create catalytically active sites which are homogeneously dispersed and uniform in their structure by grafting organometallic precursors on well defined metallic surfaces. For example, tetrabutyltin reacts with the surface of metallic particles supported on silica leading to f...

the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
15 صفحه اولThermal Stability of Nanostructurally Stabilized Zirconium Oxide
Nanostructurally stabilized zirconium oxide (NSZ) hard transparent fi lms were produced without chemical stabilizers by the ion beam assisted deposition technique (IBAD). A transmission electron microscopy study of the samples produced below 150 °C revealed that these fi lms are composed of zirconium oxide (ZrO2) nanocrystallites of diameters 7.5 ± 2.3 nm. X-ray and selected-area electron diffr...
