Porous Microreactor Chip for Photocatalytic Seawater Splitting over 300 Hours at Atmospheric Pressure (IMAGE)
Caption
- A film-type Ag3PO4/CdS photocatalyst in a porous substrate configuration is designed and prepared to avoid photocorrosion and ensure outstanding firmness.
- Both the S and Ag vacancy-rich surface and the heterojunction within the space charge region are found to be the key for high solar-to-hydrogen efficiency and excellent stability in seawater over 300 h.
- The first fully solar-driven hydrogen production prototype is constructed to work outdoors, exhibiting a high H2 evolution rate of 68.01 mmol h−1 m−2.
