Fe3O4 doped calcium aluminate nanoparticles were synthesized by co-precipitation method, an effectiveroute to synthesize novel photocatalyst to enhance the photocatalytic decolourization of acid yellow23 dye. The structural and surface morphologies were investigated using techniques such as SEM andEDAX. In this study, a degradation of acid yellow 23 dye have been carried out in the presence ofsunlight. It was observed that the synthesized Fe3O4 doped calcium aluminate photo catalyst was veryuseful in degrading the dye entirely within a short span of time (90 min). The impact of variousoperating parameters on acid yellow 23 including the amount of photocatalyst, dye concentration,H2O2 concentration and temperature was thoroughly examined. The kinetic studies explained that thedegradation of photocatalytic reaction showed pseudo first-order reaction.
