Supported copper oxide nanoparticles are a potential candidate for replacing the rare and expensive precious metals within the automotive three-way catalyst. However, a well-designed dispersion method is necessary to allow a stable high loading of active material, compensating its lower intrinsic activity and stability. In this work, a CuO-loaded SBA-15 catalyst has been manufactured by two met...

Bromate (BrO(3)(-)) in drinking water is traditionally seen as an ozonation byproduct from the oxidation of bromide (Br(-)), and its formation during chlorination is usually not significant. This study shows enhanced bromate formation during chlorination of bromide-containing waters in the presence of cupric oxide (CuO). CuO was effective to catalyze hypochlorous acid (HOCl) or hypobromous acid...

Abstract A novel nanocomposite was prepared by hybridizing polyacrylic acid/maleic acid with nano copper oxide (PAACMA/CuO) for the sorption of 60 Co (II) and 152+154 Eu (III) radionuclides from an aqueous solution. Nano-CuO biochemically produced hydrolysing its salt in presence Aspergillus terreus fungus. The PAACMA/CuO characterized using a variety analytical techniques. optimum conditions (...

In this work, we presented a surface mechanical attrition treatment (SMAT)-assisted approach to the synthesis of one-dimensional copper oxide nanowires (CuO NWs) for nanodevices applications. The as-prepared CuO NWs have diameter and the length of 50 ~ 200 nm and 5 ~ 20 μm, respectively, with a preferential growth orientation along [1 [Formula: see text] 0] direction. Interestingly, nanofield-e...

In this paper, two double helical dinuclear copper(II) complexes of bis-N,O-bidentate Schiff base ligands bis(3-methoxy-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L1) and bis(5-bromo-N-salicylidene-4,4'-diaminodiphenyl)sulfone (L2) were prepared and characterized by elemental analyses (CHN), as well as thermal analysis. Elemental analyses (CHN) suggested that the reaction between ligands and ...

Speciation of copper in waste incineration fly ashes (dry scrubber (DS) and bag filter (BF)) has been studied by X-ray absorption near edge structural (XANES) spectroscopy in the present work. Copper species such as metallic Cu, CuO, Cu(OH)2, and a small amount of CuCO3 in the fly ashes could be distinguished by semi-quantitative analysis of the edge spectra. Interestingly, nano CuO (37%) were ...

NOVEL HETEROGENOUS AND MAGNETICALY SEPARABLE CATALYSTS FOR SELECTIVE AND ENANTIOSELECTIVE ORGANIC TRANSFORMATIONS A brief description of the chapters in the thesis is outlined below: Chapter 1 Chapter 2 Chapter 5 Chapter 3 Chapter 4 Section B Section A THESIS CHAPTER-I, describes the various catalysts/process options available for an industrial chemist to effect different organic transformation...

in this paper, cuo nanoparticles  have been synthesized via solid-state thermal decomposition using copper(ii) schiff base complexes as new precursors at 600ºc under air atmosphere for 3 h. surface morphology of the products were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd) and scanning electron microscopy (sem).

Understanding the effect of copper oxide (CuO)–decorated zinc nanotube on carbon monoxide (CO) adsorption is crucial for designing a high-performance CO gas sensor. In this work, sensing properties oxide–decorated (CuO-ZnO) are studied theoretically by employing first-principles density functional theory first time. The stability, mechanism, states, and change in electrical conductivity studied...
