Nanocomposites comprising plasmon active metal nanostructures and semiconductors have been used to control the charge states in the metal to support catalytic activity. In this context dichalcogenides when combined with metal oxides offer the potential to control charge states in plasmonic nanomaterials. Using a model plasmonic mediated oxidation reaction -amino thiophenol ↔ -nitrophenol, we show that through the introduction of transition metal dichalcogenide nanomaterial, reaction outcomes can be influenced, achieved through controlling the occurrence of the reaction intermediate dimercaptoazobenzene by opening new electron transfer routes in a semiconductor-plasmonic system. This study demonstrates the ability to control plasmonic reactions by carefully controlling the choice of semiconductors.
包含等离子体活性金属纳米结构和半导体的纳米复合材料已被用于控制金属中的电荷态以支持催化活性。在这种情况下，二硫属化物与金属氧化物结合时，具有控制等离子体纳米材料中电荷态的潜力。通过一个模型等离子体介导的氧化反应——对氨基硫酚↔对硝基苯酚，我们表明，通过引入过渡金属二硫属化物纳米材料，可以通过在半导体-等离子体系统中开辟新的电子转移途径来控制反应中间体二巯基偶氮苯的生成，从而影响反应结果。这项研究证明了通过谨慎选择半导体来控制等离子体反应的能力。
