Description
Summary:In the present work, a facile synthesis of beta-cobalt hydroxide (ß-CoOH) nanosheets from ZIF-67 structure using thermolysis method has been described. The cobalt hydroxide nanosheets grown on carbon cloth would be highly benificial for wide-ranging applications including catalysis and batteries. The XRD studies show that the crystallite sizes are below 100 nanometers for both the ZIF structure and the derived CoOH. The compositional analysis shows that cobalt contributed more to the weight percentage. FESEM images reveal that cobalt nanosheets were grown on the carbon fiber. Also, the TEM images show that nanosheets morphology has been exhibited on the surface of carbon cloth because of the CoOH coating. Further, the chemical composition and purity of the (ß-CoOH) nanosheets on CC were perceived using EDX and XPS analyses.
