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...

When organic dye-containing wastewater from textile industries are sometimes released into the environment, liquids tend to pollute environment whilst their solid residue accrues on land after evaporation of water. Most these synthetic compounds known be poisonous and carcinogenic living organisms. For this study, a relatively simple, sustainable cost-effective approach have been utilized synth...

In this paper, we reported that the annealing at temperatures of 400 and 500 oC in air for 2 hours led to formation rod-like structures cupric oxide thin films prepared by chemical bath deposition technique. The structure optical properties were studied investigate role on films. morphology as-deposited CuO is almost structureless. However, are converted shapes nano-structures after annealing, ...

This study is conducted to explore the effective and stable electrode materials for electrochemical reduction of CO2. The different compositions (3 - 8%) CuO-supported CNT samples were prepared by a traditional sol-gel method, characterized TGA, SEM, TEM, FTIR XRD. characterization results confirmed uniform impregnation CuO on defects CNT's, which improved utilization meso microporous distribut...

Density functional calculations are performed to study the magnetic order of the severely distorted square planar cupric oxide (CuO) and local spin disorder in it in the presence of the transition metal impurities M (= Cr, Mn, Fe, Co and Ni). The distortion in the crystal structure, arisen to reduce the band energy by minimizing the covalent interaction, creates two crisscrossing zigzag spin-1/...
