環境目前是處於惡化的階段如何運用能源是未來的重大課題，在眾多能源中光能是被稱作取之不盡，用之不竭的能量。然而因地域問題在有光的地方才可利用，氫能補足地域問題只要儲存得當就可以隨身攜帶，兩者的結合產生光電產氫更是未來注目的焦點。
　　本實驗先以降低汙染為優先故選擇氧化鐵，氧化鐵眾多選擇Fe3O4（magnetite）α-Fe2O3（Hematite），以Fe3O4為主使用不同的界面活性劑控制pH值達到兩者比例有差別。在產氫方面製作氧化鐵電極並另外用氧化鐵磁特性控制膜厚來做到區別，使用的光源也特選三種可見光源雖都囊括可見光區。效率上最好有達到12.61%主要的由一定比例的Fe3O4和α-Fe2O3組成的氧化鐵電極。

Deterioration of the environment is now at the stage of how to use the energy of the future a major issue, in light of the many energy is referred to as an inexhaustible energy. However, due to problems in the light of the local area can make use of, hydrogen stored properly complement regional problem as long as you can carry, the combination produces photovoltaic hydrogen production is the next focus of attention.
This study, the first priority in order to reduce pollution of the selected oxide, iron oxide great selection of Fe3O4 (magnetite) α-Fe2O3 (Hematite), to Fe3O4-based surfactants with different pH to control the ratio between the difference. In terms of hydrogen production and the production of iron oxide electrode control magnetic properties of iron oxide in addition to do the film thickness difference between the light source used is also selected three kinds of visible light, although both include the visible region. Efficiency is best to have reached 12.61% mainly by a certain percentage of Fe3O4 and α-Fe2O3 iron oxide electrode composed.
