Abstract:
It has been a long‐standing demand to design hetero‐nanostructures for charge‐flow steering in semiconductor systems. Multi‐component nanocrystals exhibit multifunctional properties or synergistic performance, and are thus attractive materials for energy conversion, medical therapy, and photoelectric catalysis applications. Herein we report the design and synthesis of binary and ternary multi‐node sheath hetero‐nanorods in a sequential chemical transformation procedure. As verified by first‐principles simulations, the conversion from type‐I ZnS‐CdS heterojunction into type‐II ZnS‐(CdS/metal) ensures well‐steered collections of photo‐generated electrons at the exposed ZnS nanorod stem and metal nanoparticles while holes at the CdS node sheaths, leading to substantially improved photocatalytic hydrogen‐evolution performance.
