A facile light-mediated preparation of small palladium nanoparticles (PdNPs) with a diameter of 1.3 nm and low dispersity by using low-priced and readily prepared photoactive polymers is presented. These polymers act as reagents for the photochemical reduction of Pd ions and they are also stabilizers for the PdNPs generated in situ. The PdNP-polymer hybrid materials prepared by this reliable approach are efficient hydrogenation catalysts that show high activity and Z-selectivity in the semi-hydrogenation of alkynes. These PdNP-catalyst hybrid materials can be readily recycled and reused up to five times.
本文介绍了一种简便的光介导方法，通过使用低价且易于制备的光活性聚合物，制备出直径为1.3 nm且分散性低的小尺寸钯纳米颗粒（PdNPs）。这些聚合物充当Pd离子光化学还原的试剂，同时也是原位生成的PdNPs的稳定剂。通过这种可靠方法制备的PdNP-聚合物杂化材料是高效的加氢催化剂，在炔烃的半加氢反应中表现出高活性和Z选择性。这些PdNP-催化剂杂化材料可以很容易地回收再利用，最多可重复使用五次。
