碩士 === 國立東華大學 === 材料科學與工程學系 === 101 === 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.
