Abstract
Palladium nanoparticles have been deposited onto imidazolium bromide-functionalized ionic MWCNTs through hydrogen reduction of Na2PdCl4 in water without aid of surfactants under extremely mild conditions, and combined with an ionic liquid to create a new recyclable ionic liquid-based catalytic system allowing up to 50 times recycling.
摘要
在极其温和的条件下，通过在水中用氢气还原Na2PdCl4，在不借助表面活性剂的情况下，将钯纳米颗粒沉积到溴化咪唑功能化的离子型多壁碳纳米管上，并与离子液体结合，创建了一种新的可循环使用的离子液体基催化体系，该体系可循环使用多达50次。
