Reactor for Photocatalytic Hydrogen Production from Water

Abstract

Solar-energy-driven photocatalytic water (H₂O) splitting converts solar energy into a high-valuable chemical, i. e. hydrogen (H₂), and is thereby a promising technique for achieving a sustainable society. However, photocatalytic H₂O splitting have not been applied at a scalable industrial level yet. In addition to photocatalyst, reactor is also a crucial factor affecting efficiency of photocatalytic H₂O splitting. There are a large number of works focusing on photocatalytic H₂O splitting, including both reviews and research works. However, the reported works on photocatalytic H₂O splitting paid little attentions on reactor. Herein, we discuss recent progresses on reactor for photocatalytic H₂O splitting, and highlight challenges for further studies. This is helpful for further improving efficiency of photocatalytic H₂O splitting.
