文摘
- •
A highly crystallized tetragonal β-In2S3 exhibits a partial ordering of In3 + vacancy.
- •
It contained flower-like spherical particles, further composed of very thin petals.
- •
Tetragonal β-In2S3 has an intrinsic photocatalytic water reduction activity.
- •
The optimal H2 evolution rate was 442 μmol/h/g under pure visible light irradiation.
- •
Nitrate conversion rate achieved 3.26 mg N/h under the irradiation of a Xe lamp.
