Abstract

The construction of hybrid junctions remains challenging for the rational design of visible light-driven photocatalysts. Herein, InS/CdS/N-rGO hybrid nanosheets were successfully prepared via a one-step pyrolysis method using deep eutectic solvents as precursors. Benefiting from the surfactant-free pyrolysis method, the obtained ultrathin hybrid nanosheets assemble into stable three-dimensional self-standing superstructures. The tremella-like structure of hybrid InS/N-rGO exhibits excellent photocatalytic hydrogen production performance. The hydrogen evolution rate is 10.9 mmol·g·h, which is greatly superior to CdS/N-rGO (3.7 mmol·g·h) and InS/N-rGO (2.6 mmol·g·h). This work provides more opportunities for the rational design and fabrication of hybrid ultrathin nanosheets for broad catalytic applications in sustainable energy and the environment.

摘要

对于可见光驱动光催化剂的合理设计而言，混合结的构建仍然具有挑战性。在此，以深共熔溶剂为前驱体，通过一步热解方法成功制备了InS/CdS/N-rGO混合纳米片。受益于无表面活性剂的热解方法，所获得的超薄混合纳米片组装成稳定的三维自立超结构。混合InS/N-rGO的银耳状结构表现出优异的光催化产氢性能。析氢速率为10.9 mmol·g·h，大大优于CdS/N-rGO（3.7 mmol·g·h）和InS/N-rGO（2.6 mmol·g·h）。这项工作为合理设计和制造用于可持续能源和环境中广泛催化应用的混合超薄纳米片提供了更多机会。
