A facile and general strategy is presented to create well‐defined heterojunctions with ultra‐small multimetallic sulfide nanoparticles (MMSNPs) uniformly coated on sliver nanowires. A unique aspect of this method is the atomic‐level pre‐integration of multimetallic components by exploiting recently developed supertetrahedral metal sulfide nanoclusters. The use of such nanoclusters also enables the convenient formation of the ultrathin interfacial Ag2S layer via etching. The heterojunctions (denoted as MMSNPs/Ag2S/Ag‐NWs) benefit from adjustable multimetallic components and display tunable visible‐light‐driven photocatalytic performance owing to the synergistic effect of multimetallic components from MMSNPs and the high carrier mobility of Ag‐NWs. The synthetic strategy opens new routes to designing and fabricating various heterojunctions with multimetallic components, which could further expand their applications in catalysis, electronics, and photonics.
