چکیده
Abstract CuO nanoparticles doped with various concentrations of ZnO (5, 10, and 15 mol%) were synthesized by using the solution combustion method. The as-synthesized characterized x-ray diffractometer (XRD), scanning electron microscope (SEM), transmission (TEM), UV–Vis spectroscope. XRD analysis revealed that physical parameters such as crystallite size lattice affected after doping ZnO. spectrum showed an enhanced absorption narrowed down bandgap from 2.6 eV to 2.16 resulted in increasing optical activity. photocatalytic activities sample investigated degradation organic dyes direct green (DG) fast blue (FB) under UV light irradiation. highest efficiency is obtained (10 at 95.15% 76.4% for DG FB dyes. electrochemical properties Zn-CuO performed cyclic voltammetry results confirmed enhancement redox potential output. These CuO@ZnO electrodes also displayed capacity detect extremely dangerous chemical like arsenic.

متن کاملInvestigating structural, optical and photocatalytic properties of hydrothermally synthesized ZnO nanorod arrays with various aspect ratios
ZnO nanorods with various aspect ratios (by changing the time of growth between 0-240 min) were synthesized using hydrothermal method and were investigated using XRD, SEM, UV–Vis and PL. It was found that growth time is directly coupled with the length, orientation and aspect ratio of the nanorod arrays. The optical transmittance of the NR arrays indicated a regular decrement of average transmi...
