The cobalt doped Zinc oxide/Carbon photocatalyst was prepared by solution combustion method. The prepared photocatalyst was tested for its antibacterial activity against the clinical pathogens Escherichia coli, Klebsiella pneumaniae, Pseudomonas aeruginosa and Staphylococcus aureus. Antibacterial activity was performed by using well diffusion method. No activity was observed against Escherichia coli and Klebsiella pneumoniae at all the concentrations but positive activity was observed against Pseudomonas aeruginosa and Staphylococcus aureus. The surface area of this nanocomposite was calculated by Brunaeur-Emmet-Teller method. The average crystallite size was evaluated using X-ray diffractometer. Elemental analysis was performed by energy dispersive X-ray spectroscopy analysis. Fourier transformation infrared spectroscopy and ultraviolet – diffuse reflectance spectroscopy were also performed. This catalyst was also tested for its photocatalytic activity, by its decolorizing effect of an azo dye namely acid yellow 110 under UV light and the influence of various parameters on degradation of the dye was investigated.
