- •
Highly efficient and stable Ni(OH)<sub>2sub>/CdS/ZnIn<sub>2sub>S<sub>4sub>/TiO<sub>2sub> photoanode was synthesized.
- •
Annealing improves the FTO and TiO<sub>2sub> interface for efficient electron transport.
- •
Cocatalyst stabilizes photoelectrode through hole trapping.
- •
The simultaneous counter-directed electron-hole transfer is well proposed.
