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.
