Most of previous researches on photocatalytic water splitting for H2 are focused on the photocatalysts synthesis. High quantum yields have been reported. However, H2 and O2 must be separated in the scale-up process to avoid the potential explosion. The objective of this proposal is to develop a chemical reactor system that can separate hydrogen and oxygen during photocatalytic water splitting. This commercially safe process for hydrogen production will be used to initiate the future project of solar hydrogen in the Institute of Nuclear Energy Research (INER). The research will collaborate with Professor M. Anpo, Japan, who will provide a photochemical technique to produce hydrogen from water splitting. An H-type glass reactor will be designed and used to perform the water splitting. Two aqueous compartments are divided by the catalyst and ion-exchange films so that hydrogen and oxygen can be generated into two streams. The catalytic water splitting will also be carried out using Sunlight, and evaluated its quantum efficiency. In order to transfer such technology to the INER. Various catalyst films will be synthesized using the sputtering equipment at the INER based on the preparation conditions provided by Anpo`s group. The INER will have high-performance TiO2 based catalyst films, and perform the photocatalytic water splitting using Sunlight. The result is expected to be a competitive solar-hydrogen system compared with other methods. Such process would be a great contribution in sustainable energy.光催化反應太陽能氫水分解永續能源photocatalysissolar energyhydrogenwater splittingsustainable energy
