摘要:
Pd作为高活性的贵金属催化剂为提高Pd催化剂的,采用具有光热效应的MoS2作为载体,设计并制备Pd/MoS2复合纳米催化剂。首先通过水热法合成MoS2,片径约为00~300 nm,厚度约为7 nm)组装而成。利用还原法在MoS2的表面Pd纳米颗粒,直径约为11 nm。Pd/MoS2花状超结构作为催化剂研究了激光加热和油浴加热两种条件下的铃木偶联反应808 nm的激光 W/cm2,激光加热带来的溶液温度从29.4升高到60.8 °C,相应的光热催化产率从30.5%提高到86.3%,明显高于油浴加热同等温度下的热催化产率(24.3%~60.4%)。例如,当反应温度为40 °C时,光热催化的1.5倍Pd/MoS2花状超结构展现了较好的光热催化性能,为设计高活性的铃木偶联反应催化剂提供了新思路。
Abstract:
Pd has been widely used as a highly active noble metal catalyst for organic reactions such as Suzuki coupling reaction. To improve its catalytic performance for Suzuki coupling reaction, Pd/MoS2 flower-like superstructures were designed and prepared by using MoS2 with photothermal effect as the carrier. Firstly, MoS2 flower-like superstructures were synthesized by a simple hydrothermal method, and they were constructed from nanosheets with diameters of about 200~300 nm and thicknesses of about 7 nm. Pd nanoparticles with diameters of about 11 nm were loaded on the surface of MoS2 by a reduction route. Subsequently, by using Pd/MoS2 flower-like superstructures as the catalyst, the conversion efficiency of Suzuki coupling reaction was investigated under both laser heating and oil bath heating conditions. When the intensity of 808 nm laser as heating sources went up from 1 to 4 W/cm2, the equilibrium temperature of solution from laser heating increased from 29.4 to 60.8 °C. Accordingly, the photothermal catalysis yield enhanced from 30.5% to 86.3%, which was significantly higher than the thermocatalytic yield (24.3%~60.4%) at the same temperature from oil bath heating. For example, when the reaction temperature was 40 °C, the photothermal catalysis rate was 1.5 times as high as the thermal catalysis. Therefore, Pd/MoS2 flower-like superstructures show good photothermal catalytic performance, which assists in the design of highly active catalysts for Suzuki coupling reaction
