Cobalt doped Zinc Oxide/Carbon nano composite was synthesized by solution combustion method and characterized by X-ray diffractometer, field emission scanning electron microscope  and energy dispersive X-ray spectroscopy  analysis. This composite shows X-ray diffraction pattern that matched with nano particle of ZnO with wurtzite structure and average grain size was found to be 10.53 nm. .  Further the presence of the elements like C, Co, Zn and O was confirmed by energy dispersive X-ray spectroscopy analysis.   The effect of Co doping on the photocatalytic activity was investigated by photo degradation of the dye, acid blue 113. This nano composite exhibited better photocatalytic activity when compared to nano ZnO and nano ZnO/C composites.
