In a previous publication, ball milling was introduced as an effective method for the preparation of supported metal catalysts, simply from coarse powders and oxide support. this follow-up study, we demonstrate that mixing multiple sources can result in alloyed nanoparticles, extending field application to synthesis bimetallic catalysts. Ball Au Pd or Cu high-energy regime (shaker mill) indeed ...

An investigation was carried out to study the feasibility of using 5% nickel/alumina catalysts synthesized with different methods and metal precursors for hydrogenation tetralin. The were characterized atomic absorption spectroscopy, thermogravimetric analysis, X-ray powder diffraction, photoelectron spectroscopy (XPS), hydrogen chemisorption, surface area pore volume analyses. tested in a cont...

in this research, different alcohols and phenols are subjected to the reaction with hmds in the presence of ionic liquid and silica-supported catalysts. silylation was accomplished under mild reaction conditions at room temperature in short reaction times and good to excellent yields.
