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.

多金属硫化物纳米粒子和银纳米线的高度可调异质结

提出了一种简便，通用的策略，用均匀分布在银纳米线上的超小型多金属硫化物纳米粒子（MMSNPs）创建定义明确的异质结。该方法的一个独特方面是通过利用最近开发的超四面体金属硫化物纳米团簇，对多金属组分进行原子级的预集成。通过使用这样的纳米团簇，也可以通过蚀刻方便地形成超薄界面的Ag ₂ S层。异质结（表示为MMSNPs / Ag ₂S / Ag-NWs得益于MMSNPs的多金属组分的协同作用以及Ag-NWs的高载流子迁移率，可调节的多金属组分受益于其显示可调的可见光驱动的光催化性能。合成策略为设计和制造具有多金属成分的各种异质结开辟了新途径，这可能会进一步扩展其在催化，电子学和光子学中的应用。
