A photocatalyst supported on magnetic material allows the simple technique by using an external magnetic material to separate photocatalyst from the treated water. Thus, it is a magnetically separable nanoparticles photocatalyst (MSNP). The use of superparamagnetic nanoparticles that do not pose spontaneous magnetic moment thus could be dispersed in water and can be recollected easily by an external magnetic bar. We prepare Fe₃O₄/SiO₂/TiO₂ composite by hetero agglomeration of Fe₃O₄/SiO₂ and TiO₂ at a pH range of 3 to 6.2 in an aqueous slurry_.The Fe_{3 …}
