The effect of pectin, gellan, and chitosan on the activity, stability, and styrene selectivity of supported palladium catalysts for the selective hydrogenation of phenylacetylene was determined. It was shown that a positive effect is achieved as a result of the formation of palladium nanoparticles with a size of 1-4 nm, which are distributed relatively uniformly over the surface of the carriers, when polysaccharides are added in the catalytic system.

苯乙炔加氢中多糖稳定的纳米催化剂

测定了果胶、结冷胶和壳聚糖对用于苯乙炔选择性加氢的负载钯催化剂的活性、稳定性和苯乙烯选择性的影响。结果表明，当在催化体系中加入多糖时，形成了尺寸为 1-4 nm 的钯纳米颗粒，这些纳米颗粒相对均匀地分布在载体表面，从而获得了积极的效果。
