Structural and thermal properties of pure and chromium doped zinc oxide nanoparticles

Abstract Pure ZnO and Cr-doped nanoparticles have been synthesized via a facile chemical co-precipitation route their structural, thermal characteristics were discussed systematically. In the experimental producer, doping concentration has varied range, 0.05–0.1 M, while calcined at 600 °C. The influence of Cr-doping on physical was investigated addressed. As-prepared samples analyzed XRD, FTIR, TGA/DTA, BET, ICP-MS. XRD analysis shows that Cr doped with average particle sizes between 23 39 nm successfully developed hexagonal wurtzite structure. FTIR spectroscopy confirms existence chromium in formation ZnO. TGA/DTA Cr–ZnO are more thermally stable than nanoparticles. Moreover, dopant ICP-MS showed good agreement expected concentration. BET surface area measurement 176.25 m 2 /g 287.17 for un-doped ZnO, 0.1 M nanoparticles, respectively. Hence, enhances stability. Thus, show stability, high area, which is an excellent characteristices nanomaterials. Graphic abstract
