In the present study, zinc oxide (ZnO) and magnesium doped (Zn0.5Mg0.5O) nanoparticles were synthesized by simple cost-effective co-precipitation method. The materials characterized X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, Field Emission Scanning Electron Microscopy (FESEM) with Energy dispersive spectrum (EDAX). Finally, effect of (Mg) doping on structural, morp...

In this paper, the structural and optical properties of ZnO-SiO2-based ceramics fabricated from oil palm empty fruit bunch (OPEFB) were investigated. The OPEFB waste was burned at 600, 700 800 °C to form ash then treated with sulfuric acid extract silica ash. X-ray fluorescence (XRF) diffraction (XRD) analyses confirmed existence SiO2 in sample. Field emission scanning electron microscopy (FESE...
