In this work iron-gold nanocomposites were synthesized by both sono-chemical and ball miling methods and the results were compared with each others. Firstly iron nanoparticles as a magnetic cores were prepared by both wet chemical and solid state method, also gold nanoparticles as photocatalyst phase were coated on the iron cores. As we expected the results show with sonochemical method smaller nanoparticles and the most uniform nanoparticles in comparison to ballmilling method were obtained. Both up to down (ballmilling) procedure and down to up (sono-chemical) were analyzed in comparison to each other. Aromatic azo dyes are one of the samples of cancerous agent so in this work, photo-catalyst activities of nanocomposites were investigated by photo-degradation of methyl red under ultra-violet irradiation.
