Metal NP @ metal-organic frameworks (MOFs) are widely used in electrocatalysis. However, many of the MOFs are poorly conductive. Here, we loaded bismuth (Bi) into a Zr-based MOF of the UiO structure that is active for CO reduction to formate and found that a moderate conductivity of the nanosized MOFs is sufficient to support a reasonably high catalytic current density. This finding allows simpler catalyst design and quantitative rationalization of MOF electrocatalysis.
金属纳米颗粒@金属有机框架（MOF）被广泛应用于电催化领域。然而，许多MOF的导电性较差。在此，我们将铋（Bi）负载到具有UiO结构的锆基金属有机框架中，该框架对将CO还原为甲酸盐具有活性，并且发现纳米尺寸的MOF具有适度的导电性足以支持相当高的催化电流密度。这一发现使得MOF电催化的催化剂设计更简单且能进行定量合理化分析。
