Abstract
A uniformly dispersed two-phase Cu/Cu2O NPs@graphene was obtained via an innovative "take" and "off" synthesis strategy with a Cu-MOF-derived jacket structure. The electron transfer between the Cu phase and Cu2O phase leads to the synergistic effect of the Cu(0)-Cu(i) phase for an efficient catalysis of the Sonogashira cross-coupling reactions.
摘要
通过一种创新的“获取”和“去除”合成策略以及具有铜基金属有机框架衍生外壳结构，获得了一种均匀分散的两相Cu/Cu2O纳米颗粒@石墨烯。铜相和Cu2O相之间的电子转移导致Cu(0)-Cu(i)相的协同效应，从而高效催化Sonogashira交叉偶联反应。
