文摘
- •
We prepared Ce, Ce2O3 and CeO2 cocatalysts modified TiO2 nanotube arrays catalyst.
- •
The modified catalyst showed higher photoconversion efficiency in white or visible light.
- •
The flat band potential of the modified catalyst indicated negative movement.
- •
The catalyst can split pure water to produce hydrogen without external voltage.
- •
A stable H2 generation property was obtained with the highest efficiency of 6.1%.
