We report three well-defined types of Au nanoparticles (NPs) protected by rigid macrocyclic cucurbit[n]uril (CB[n]) (CB[n]-Au), which are prepared via the supramolecular self-assembly of the precursors. CB[n]-Au shows excellent catalytic activity and selectivity, with a performance that can be maintained for up to 72 h in the electroreduction of CO to CO. The effects of the structural features of different CB[n]s on the electrocatalytic performance of the Au NPs have been revealed for the first time.
我们报道了由刚性大环葫芦[n]脲（CB[n]）保护的三种明确类型的金纳米颗粒（NPs）（CB[n]-Au），它们是通过前体的超分子自组装制备的。CB[n]-Au表现出优异的催化活性和选择性，在将CO电还原为CO的过程中，其性能可保持长达72小时。首次揭示了不同CB[n]的结构特征对金纳米颗粒电催化性能的影响。
