文摘
- •
“Giant” CdSe@CdS QDs sensitized TiO2 photoanode is applied for efficient H2 production.
- •
Electronic band structure can be modulated and regulates the efficiency of charge transfer.
- •
Unprecedented photocurrent density (~10 mA/cm2) for “giant” QD-based PEC is obtained.
- •
Pt-free and highly stable devices are produced using low-cost materials.
