Abstract

The invention provides a light condensation-light conversion composite reinforced type solar photocatalysis water-decomposition hydrogen-production system. The system comprises a solar collection-transmission unit, a light conversion-photocatalysis hydrogen-production reaction unit, a light conversion-photocatalysis oxygen-production reaction unit and a medium cycle control unit. By adopting the dual action of light condensation and light conversion, the response spectral intensity of the photocatalysis is remarkably enhanced, and the medium cycle control unit forcefully ensures the loop exchange and the stable concentration of a reaction medium component. With multiple actions, a photocatalysis material can favorably interact with a reaction medium to generate a high-efficiency and stable photocatalysis hydrogen-production reaction. The system has the advantages of simple structure, strong designability, high photon conversion efficiency, stable performance, and the like, can fully convert and utilize solar energy and suit different sunshine conditions and is easy to popularize and apply on a large scale.
