文摘

•: A highly crystallized tetragonal β-In₂S₃ exhibits a partial ordering of In^3 + 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.
