The integration of the second material with unique properties into original material to fabricate heterostructure represents an effective strategy to enhance photocatalytic H evolution. Herein, we synthesized a MoS/ZnInS heterostructured photocatalyst using a two-step hydrothermal method. The resulting MoS/ZnInS displayed the flower-like morphology formed by staked nanosheets, significantly accelerating photocatalytic H evolution performance. The optimal MoS/ZnInS (ZIS/Mo-50) achieved remarkable photocatalytic H production rate of 20.5 mmol g h, which is 18.5 times higher than that of pristine ZnInS. Further characterizations proved that the formation of the MoS/ZnInS heterostructure adjusted the energy band structure of ZnInS, enhancing its light absorption capability. Additionally, the heterostructure facilitated efficient charge separation and transfer. These enhancements notably boosted the photocatalytic H evolution, providing a promising example for designing efficient photocatalysts for H evolution.
将具有独特性质的第二种材料与原始材料整合以制备异质结构是增强光催化析氢的有效策略。在此，我们采用两步水热法合成了一种MoS/ZnInS异质结构光催化剂。所得的MoS/ZnInS呈现出由堆叠纳米片形成的花状形态，显著加速了光催化析氢性能。最佳的MoS/ZnInS（ZIS/Mo-50）实现了20.5 mmol g h的显著光催化产氢速率，比原始的ZnInS高18.5倍。进一步的表征证明，MoS/ZnInS异质结构的形成调整了ZnInS的能带结构，增强了其光吸收能力。此外，异质结构促进了有效的电荷分离和转移。这些增强显著提高了光催化析氢性能，为设计高效的析氢光催化剂提供了一个有前景的范例。
