Metal–organic framework assisted and in situ synthesis of hollow CdS nanostructures with highly efficient photocatalytic hydrogen evolution

Hollow CdS nanoboxes with a specific surface area of 153 m² g⁻¹ are synthesized through in situ sulfurizing Cd-MOF-47 with thiourea, which exhibit a greatly improved photocatalytic activity in water splitting to hydrogen (21 654 μmol g⁻¹ h⁻¹).
