ABSTRACT In this paper, novel Nanohybrid CuO-Fe3O4/Zeolite nanocomposites (HCFZ NCs) have been synthesized to improve the adsorption capacity and activity for removing the Arsenic and Lead cations from the contaminated water solutions. The nanohybrid 4, 10, and 20 -HCFZ NC samples were investigated by XRD, FT-IR, TEM, FESEM, EDX, and BET. The characterization results of these catalysts confirm...

Green synthesis methods using plants have many advantages such as time-saving, chemical-free, and negative effects on the environment. So, extracted Citrus aurantium juice was used to synthesize green CuO/TiO2 and(G- CuO/TiO2) nanocatalyst which characterized by XRD, SEM, EDX, FTIR, BET, ZP utilized in degradation of methylene blue (MB) under UV lamps dark environments. The ANOVA program maximi...

Composites of transition metal oxides (TMOs)/polymers have many modern technological, industrial, and biological applications. Co3O4 CuO nanoparticles (Nps) were synthesized by sol–gel. Then they are doped into poly(methyl methacrylate) (PMMA) via the solution casting method. The obtained Nps nanocomposites then investigated using several techniques. XRD HR-TEM indicated high purity face-center...

Mesoporous CuO-ZrO2 catalysts were prepared and calcined at 500 ̋C. The performance of the synthesized catalysts for benzylation of benzene using benzyl chloride was studied. The bare support (macroporous ZrO2) offered 45% benzyl chloride conversion after reaction time of 10 h at 75 ̋C. Significant increase in benzyl chloride conversion (98%) was observed after CuO loading (10 wt. %) on porous ...

The hollow CuO@SiO2 spheres with a mean diameter of 240 nm and a thin shell layer of about 30 nm in thickness was synthesized using an inorganic SiO2 shell coating on the surface of Cu@C composite that was prepared by a two-step hydrothermal method. The obtained hollow CuO@SiO2 spheres were characterized by ICP-AES, nitrogen adsorption-desorption, SEM, TEM, XRD, H2-TPR, CO-TPR, CO-TPD and NO-TP...

Energy storage is of particular importance for the use alternative energy sources. One new and efficient procedures in thermal (TES) appropriate form using phase change materials (PCM). PCMs store latent heat (LH) melting without mechanical tools, entirely intelligently, or anything other than their intrinsic propensity to spontaneously phases, adapt environmental changes, actively seek ways le...

Various CuO nanostructures have been well studied as anode materials for lithium ion batteries (LIBs); however, there are few reports on the synthesis of porous CuO nanostructures used for anode materials, especially one-dimensional (1D) porous CuO. In this work, novel 1D highly porous CuO nanorods with tunable porous size were synthesized in large-quantities by a new, friendly, but very simple...
