Presentation Title

Photocatalytic water splitting for large scale solar hydrogen production


Water splitting to hydrogen and oxygen using particulate photocatalysts is one of the potential candidates to produce green hydrogen at low cost and on a large scale. To achieve solar hydrogen production based on such systems in a near future, there are several problems that need to be solved, such as development of efficient and durable photocatalysts, cost effective reactors, efficient hydrogen separation systems, ensuring safety issues, and so on. In this talk, recently developed photocatalysts, water splitting reactors and hydrogen separation systems being developed in our project will be introduced. In addition, safety issues of the total solar hydrogen production system based on particulate photocatalysts for water splitting will be discussed.
