We focus on the spinel structure as an environmental purification catalyst and synthesized CaFe₂O₄ and MgFe₂O₄ which can be from low cost materials such as iron, calcium and magnesium. We attempted dispersing them in an aqueous solution, and make pn junction to improve the photoactive performance. The malic acid method was used to obtain a homogeneous target substance. The acetic acid decomposition was performed under the simulated sunlight and it was revealed that the photoactivation performance was improved by pn junction.
