In this study, successful synthesis of ZnO nanoparticles (NPs), CuO NPs, and ZnO/CuO nanocomposite through an eco-friendly method using Corriandrum sativum leaf extract as a capping agent is reported. Using XRD, FTIR, UV-Vis, SEM techniques, the synthesized materials were characterized for structural analysis, functional groups identification, spectroscopic measurements, morphological analysis....

In the present research, an efficient process for the synthesis of propargylamine derivatives catalyzed by a novel nanocomposite of CuO/MnO2 is reported. CuO/MnO2 nano-catalyst was synthesized by the co-precipitation process and characterized by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), X-ray diffraction(XRD), ICP-OES and BET surface area an...

The goal of this research was to develop and analyse novel Zn–Co–CeO2 protective coatings on steel. Two different sources ceria (CeO2) particles were employed: commercial powder synthesized stable colloidal dispersion-sol. plating solution agitated by ultrasounds (20 30 W cm−2) or magnetic stirrer (300 rpm) during electrodeposition. CeO2 used characterized methods, namely scanning electron micr...

A unique nanocomposite of CeO2 nanoparticles and Ce-doped manganese oxide nanofibers having a crystalline cryptomelane-type octahedral molecular sieve (KMn8O16·nH2O, abbreviated as OMS-2) structure (denoted CeO2-CeOMS-2) was prepared by the reaction Ce(NO3)3 KMnO4 at 90 °C. CeO2-CeOMS-2 shows extremely high photothermocatalytic activity, very low selectivity for acetaldehyde (an unfavorable byp...

Despite significant progress having been achieved in recent years to improve wood’s durability, additional developments are still necessary to increase its color stability. ZnO and CeO2 nanoparticles were compared to UV absorbers (Tinuvin 477 DW, 292 and 5151) commonly used to stabilize the wood products color. Nanoparticles, with concentrations in the range 1 to 2 wt%, and UV absorbers, using ...

La2Zr2O7 (LZO) films were grown on different buffer architectures by radio frequency magnetron sputtering for the large-scale application of YBa2Cu3O7-x (YBCO)-coated conductors. The three different buffer architectures were cerium oxide (CeO2), yttria-stabilized zirconia (YSZ)/CeO2, and CeO2/YSZ/CeO2. The microstructure and surface morphology of the LZO film were studied by X-ray diffraction, ...
