Activity of Cu-Co-M (M= Ce, Ni, Au, Mg) catalysts prepared by coprecipitation method, calcined at high temperature for CO oxidation
The present study deals with analysis of the activity of catalysts prepared by addition of different metals to Copper and Cobalt based catalysts for CO oxidation and the variation in activity caused by changes in composition. A series of catalysts were prepared with Cu:Co molar ratio 1:4 and a third metal (M= Ce, Ni, Au, Mg) was added in three different quantities. Compositions were prepared by...

متن کاملCTAB-assisted of Fe2O3/CeO2 nanosized prepared by coprecipitation method
Recently, cerium oxide (CeO2) nanoparticles have been widely used in engineering andmedical sciences due to the diversity of their applications. Fe-Ce nanoparticles were synthesized bysimple co-precipitation method via iron nitrate (Fe(NO3)3.9H2O) and cerium nitrate (Ce(NO3)3.6H2O) asprecursor in the presence of cetyltrimethylammonium bromide (CTAB) surfactant. The samples wer...
متن کاملHigh-mobility ZrInO thin-film transistor prepared by an all-DC-sputtering method at room temperature
Thin-film transistors (TFTs) with zirconium-doped indium oxide (ZrInO) semiconductor were successfully fabricated by an all-DC-sputtering method at room temperature. The ZrInO TFT without any intentionally annealing steps exhibited a high saturation mobility of 25.1 cm(2)V(-1)s(-1). The threshold voltage shift was only 0.35 V for the ZrInO TFT under positive gate bias stress for 1 hour. Detaile...
متن کاملBlue-Emitting Small Silica Particles Incorporating ZnSe-Based Nanocrystals Prepared by Reverse Micelle Method
ZnSe-based nanocrystals (ca. 4-5 nm in diameter) emitting in blue region (ca. 445 nm) were incorporated in spherical small silica particles (20-40 nm in diameter) by a reverse micelle method. During the preparation, alkaline solution was used to deposit the hydrolyzed alkoxide on the surface of nanocrystals. It was crucially important for this solution to include Zn(2+) ions and surfactant mole...
