Abstract CuO nanoparticles doped with various concentrations of ZnO (5, 10, and 15 mol%) were synthesized by using the solution combustion method. The as-synthesized characterized x-ray diffractometer (XRD), scanning electron microscope (SEM), transmission (TEM), UV–Vis spectroscope. XRD analysis revealed that physical parameters such as crystallite size lattice affected after doping ZnO. spect...

Developing the high-efficient and green synthetic method for chiral amino alcohols is an intriguing target. We have developed the Mg(2+)-doped Cu/ZnO/Al2O3 catalyst for hydrogenation of L-phenylalanine methyl ester to chiral L-phenylalaninol without racemization. The effect of different L-phenylalanine esters on this title reaction was studied, verifying that Cu/ZnO/Al2O3 is an excellent cataly...

This paper presents a model-aided approach to the development of catalysts for CO oxidation. This is in contrast to the traditional methodology whereby experiments are guided based on experience and intuition of chemists. The proposed approach operates in two stages. To screen a promising combination of active phase, promoter and support material, a powerful “space-filling” experimental design ...

Highly powered electrostatic capacitors based on nanostructures with a high aspect ratio are becoming critical for advanced energy storage technology because of their high burst power and energy storage capability. We report the fabrication process and the electrical characteristics of high capacitance density capacitors with three-dimensional solid-state nanocapacitors based on a ZnO nanowire ...

Oxide-supported single-atom Pt materials are prepared by combining surface organometallic chemisorption with atomic layer deposition (ALD). Here Pt is supported as a discrete monatomic “pincer” complex, stabilized by an atomic layer deposition (ALD) derived oxide overcoat, and then calcined at 400 °C under O2. ALD-derived Al2O3, TiO2, and ZnO overlayers are effective in suppressing Pt sintering...

in present investigation, zno nanostructure was synthesized by means of a precipitation and sonochemical methods. the x-ray diffraction (xrd) pattern is shown that the wurtzite structure of zno has the hexagonal symmetry and there is no impurity. the average zno particles crystallite size was calculated about 41 nm. the sem and tem images reveal nanostructure zno particles with a cauliflower-li...

Metal oxide nanoparticles are used in a broad range of industrial processes and workers may be exposed to aerosols of the particles both during production and handling. Despite the widespread use of these particles, relatively few studies have been performed to investigate the toxicological effects in the airways following inhalation. In the present study, the acute (24 h) and persistent (13 we...
