The catalyst activity of fluorite-type oxide, such as ceria and zirconia, for the reduction of sulfur dioxide by carbon monoxide to elemental sulfur can be significantly promoted by active transition metals, such as copper. More than 95% elemental sulfur yield, corresponding to almost complete sulfur dioxide conversion, was obtained over a Cu-Ce-O oxide catalyst with a feed gas of stoichiometri...

The incorporation of copper species is synthesized  in a silica matrix by the sol-gel method. We have doped copper ions and copper particles using two different copper sources: Cu(NO3)2.3H2O and copper particles chemically synthesized. We can prepare the particles of copper metallic, cuprous and cupric oxide and  compare the synthesis and characterization copper species on the silica matrix.  O...

Copper oxide (CuO) nanostructures are of particular interest because of their interesting properties and promising applications in batteries, super capacitors, solar cells, gas sensors, bio sensors, nano fluids and catalysis. In Recent past, more efforts have been received to design materials with different properties which is dependent on morphology.  In this work cupric oxide nano flakes were...

Two Cu(II) complexes, [Cu(L1)2](NO3)2 (1) and [Cu(L2)2] (NO3)2(2), which L1 and L2 Schiff base ligands are 2-(thiophene-2-yl) -1H-imidazo [4,5-f] [1,10] phenanthroline and 2-(furane-2-yl)-1H-imidazo[4,5-f] [1,10] phenenthroline, respectively, were syn...

In order to measure serum copper concentration, 163 adult males working at different units of copper plant from a total population of 671, were selected by simple random sampling. Eighty three subjects working at melting foundry, 49 in extrugen- rolling and 31 at administrative service untils. Eighty four adult male natives of Kerman and it's suburbs were randomly choosen as control group, seru...

Incorporation of copper species into silica matrix was performed by the sol-gel method. Copper ions and copper particles were doped using two different copper sources; Cu(NO3)2.3H2O and copper particles chemically synthesized.The particles of copper metallic, cuprous and cupric oxide were prepared and the synthesis and characterizations of copper species were compared together. On the other han...

in this study, a feasible green method for the synthesis of copper oxide nanocrystalline is described by using sour cherry juice which has a significant effect on crystalline size, and morphology. the benefits of the green method, not only nanometer scale are formed but also low-cost method are obtained in a normal atmosphere which it has been used (ch3coo)2cu.h2o individually as cu sources. al...
