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 Ag S layer via etching. The heterojunctions (denoted as MMSNPs/Ag S/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.
本文提出了一种简便通用的策略，用于制备具有明确异质结的材料，该异质结由均匀包覆在银纳米线上的超小多金属硫化物纳米颗粒（MMSNP）构成。该方法的独特之处在于，通过利用最近开发的超四面体金属硫化物纳米簇，实现多金属组分在原子水平上的预整合。此类纳米簇的使用还能通过蚀刻方便地形成超薄界面Ag₂S层。这些异质结（表示为MMSNP/Ag₂S/Ag-NW）受益于可调节的多金属组分，并且由于MMSNP中多金属组分的协同效应以及Ag-NW的高载流子迁移率，展现出可调谐的可见光驱动光催化性能。该合成策略为设计和制造具有多金属组分的各种异质结开辟了新途径，这可能会进一步扩大它们在催化、电子和光子学领域的应用。
