The designed synthesis of nanotwin architectures and thus-induced phase junctions expresses huge significance for semiconductor photocatalysts. However, current methods of producing nanotwins mainly involve high-temperature thermal treatment and tedious reaction steps, generally resulting in large bulk structure with ill-defined morphology and low specific surface area. Here, we propose a mild ligand-assisted coordinative self-assembly method to synthesize uniform mesoporous Zn x Cd 1−x S nanospheres with ultrahigh surface areas (148−312 m 2 g −1 ) and controllable diameter (90−370 nm). Moreover, the sample possesses abundant phase junctions induced by nanotwins containing both hexagonal and cubic segments. With the synergy of the twininduced phase junctions and high surface area, the as-prepared mesoporous Zn 0.82 Cd 0.18 S nanospheres exhibit a remarkable photocatalytic H 2 evolution rate of 13.46 mmol h −1 g −1 with free noble metal. The mechanism of photocarrier dynamics was studied by transient photovoltage spectroscopy, manifesting that the photocarrier lifetime of Zn 0.82 Cd 0.18 S is largely prolonged and therefore improves the charge separation efficiency and photocatalytic activity.
