Keywords: photocatalyst, ferrite, co-precipitation, magnetism


A manganese-zinc ferrite as a magnetically separable photocatalyst was synthesized by simple co-precipitation and the following silica as well as titanium dioxide coating through sol-gel techniques. The nanoparticle was found to be well induced by external magnetic field giving high saturation magnetization. The photocatalytic property over methylene blue solution was observed and the evidence of amorphous silica inhibition to electron transferring was seen.
