Grain Growth Evaluation Of Nanostructured ZnCo2O4 For Solar Selective Absorb…

Ternary cobalt-based metal oxide (ZnCo2O4) has been successfully coated onto aluminum substrate via sol-gel method for solar selective absorber application. The aim of this study to evaluate the influence of temperature and concentration on the morphology, crystalline structure and optical properties of zinc cobalt oxide coating. ZnCo2O4 were synthesized using Co(NO3)2.6H2O and Zn(NO3)2.3H2O co…
