چکیده

The solid state reaction of CUWO4-2 formation from CuO and WO3 was studied by the contact method in air and nitrogen. The results showed that the reaction is governed by the diffusion of the W 6 + and 0 2 _ ions and that the rate determining step is the diffusion of oxygen ions in the reaction product. This is in agreement with the defect structure of copper tungstate, an n-type semiconductor with oxygen vacancies through which the diffusion process is possible.

Cu-Cr-O and Cu-Ce-O Regenerable Oxide Sorbents for Hot Gas Desulfurization

Binary Cu-Cr-O and Cu-Ce-O oxides were studied in this work as regenerable sorbents for high-temperature fuel gas desulfurization. CuO-Cr2O3 and CuO-CeO2 sorbents can remove H2S from simulated coal-derived fuel gas to less than 5-10 ppmv in the temperature range of 650-850 °C. The presence of stable CuCr2O4 in CuO-Cr2O3 solids retains some copper in the Cu2+ or Cu1+ oxidation state, which can a...

Green chemistry approach for the synthesis of CuO nanostructure

Molecular sieves MCM-41 were synthesized from rice husk ash (RHA) as alternative sources of silica. The material was synthesized by a room temperature method from a gel with the molar composition SiO2: 1.6EA: 0.215HDTMABr: 325H2O with pH correction. The cetyltrimethylammonium bromide (CTMABr) was used as a structure template. Nanocomposite containing 5.0 and 10.0 wt.% of Cu was synthesized unde...
