The aim of this research is to develop new iron complex oxide photocatalysts consisting of p/n junction in order to produce hydrogen from water. In the initial stage of this research, we studied about synthesis of p/n junction of the iron oxide, but the synthesis was very difficult. Therefore, we tried to prepare nano-hybrid photocatalyst materials containing iron oxide. We selected various layered and nanosheet oxides such as ceria, zinc oxide, graphene oxide as the mixture to iron oxide. Theses oxides had very interesting properties such as luminescence with high quantum efficiency, ferromagnetism at the organic compound/ZnO nanosheets, and high oxygen reduction catalytic activity of iron compounds. These mixtures containing iron oxides were tested as the photocatalyst for water photolysis. We have gotten some hints to prepare good catalyst, although the above hybrid catalysts did not show high activity.

本研究的目的是开发由p/n结组成的新型铁络合氧化物光催化剂，用于从水中制氢。在本研究的初始阶段，我们研究了氧化铁的p/n结的合成，但合成非常困难。因此，我们尝试制备含氧化铁的纳米杂化光催化剂材料。我们选择了各种层状和纳米片状氧化物，如氧化铈、氧化锌、氧化石墨烯作为氧化铁的混合物。这些氧化物具有高量子效率的发光、有机化合物/ZnO纳米片上的铁磁性以及铁化合物的高氧还原催化活性等非常有趣的性质。这些含氧化铁的混合物作为水光解的光催化剂进行了试验。虽然上述杂化催化剂的活性不高，但我们得到了一些制备好的催化剂的提示。
