The 20th Chinese NationalConference on Light Scattering organized by Suzhou University and Xiamen Universitywas held in Suzhou from Nov. 2-6, 2019.Lu Bai was awarded the Best Poster Award. Congratulations!
The article reported an efficientvisible-light-driven deuteration of organic halides using plasmonic Au/CdS asphotocatalyst and green D2O as deuterium donor. The highphotocatalytic activity is a result of plasmon-generated hot electrons andenhanced charge separation/transfer on the Au/CdS nanocomposites. Thedeuteration mechanism is proved to be a radical pathway in which C−X bonds areactivated by the photoinduced electron transfer to generate active arylradicals, and the aryl radicals are trapped by the D2O to give thedeuterated products. This work provides an efficient approach forvisible-light-driven deuteration under mild conditions and sheds light on theinteraction between plasmonic NPs and semiconductor, which is very helpful forrational design of photocatalyst.
