Can you give some solutions how magnetic Fe2O3 nanoparticles play a role in improving Photocatalysis with TiO2 nanoparticles. I want to know the electrochemical activity of Fe2O3 in Photocatalysis.
Are you sure that this oxide does enhance the activity of TiO2? You'd better introduce an inert layer of other phase, e.g. SiO2

Michael is absolutely right that the experiment should be performed before asking such a question.
Carefully formulate your questions.
This sentence does not make any sense: "I want to know the electrochemical activity of Fe2O3 in Photocatalysis."
The topicstarter should keep in mind that double system like magnetic phase-titania doesn't mostly exhibit improved photocatalitic activity. Just look the papers of Watson and Beydoun through. To avoid such a limitation you must create a triple system whereas the third component prevents photodissolution, charge interaction between magnetic phase and TiO2, and enhances charge separation. The latter is of vital importance during various photo-induced reactions. Good luck for the future. I hope my advice work out well for you
