| description | A n-type semiconductor ZnO has high transmittance features, excellent chemical stability and electrical properties. It is also commonly used in a range of fields, such as gas sensors, photocatalysts, optoelectronics, and solar photocell. Magnesium-doped zinc oxide (Mg-ZnO) nano powders were effectively produced using a basic chemical precipitation process at 45°C. Calcined Mg-ZnO nano powders have been characterized by FTIR, XRD, SEM-EDX and PL studies. XRD measurements from Mg-ZnO revealed development of a crystalline structure with an average particle size of 85 nm and SEM analysis confirmed the spherical morphology. Electrochemical property of produced Mg-ZnO nanoparticles was analyzed and the specific capacitance value of 729 F g–1 at 0.5 A g–1 current density was recorded and retained a specific capacitance ~100 percent at 2 A g–1 current density. |
