Structural and morphological properties of Co3O4 nanostructures: Investigation of low temperature oxidation for photocatalytic application for waste water treatment

The shape and incomparable size of synthesized Co3O4 nanostructures demonstrated using high resolution FESEM and HRTEM. The synthesized nanomaterials were considered by XRD and FTIR spectroscopy. Co3O4 nanostructures were investigated for different applications, such as, photocatalytic degradation of hazardous waste water from dyeing industry. Remarkably, the toxicity of Co3O4 have been described earlier, the toxicity is reduced by modified cost effective material through biosynthesis. Possible reaction mechanism pathways during photocatalyst into the dye solution over Co3O4 nanostructures have been proposed. In this view, the result shows, economic and green synthesis of Co3O4 nanostructures have a high applicability for the removal of waste water treatment application widely. This could be attribute to a novel Co3O4 nanostructures that favorably significant in the present environment for the removal of hazardous chemicals.
