Photocatalytic activity of the synthesized Calcium aluminate (CaAl2O4) nanoparticle with average size of 8.34 nm was assessed on Coralene Dark Red 2B azo dye in an aqueous solution under solar irradiation. The nanoparticleswere characterized byX-RayDiffraction (XRD) and scanning electron microscopy (SEM). The effect of various parameters, such as effect of pH and catalyst loading on Coralene Dark Red 2B azo dye degradation was investigated. The degradation efficiency was studied by using spectrophotometer (473nm)with the addition ofCalciumaluminate (CaAl2O4) nanoparticles (average size of 8.34nm) against Coralene Dark Red 2B azo dye (30 mg/L) and found to be very efficient in the degradation of the dye.
