多孔块体材料可用于多相气、液相催化、电催化和电催化传感，因此在催化领域具有重要的应用价值。在这种背景下，纳米多孔金获得了相当大的吸引力，因为它是腐蚀衍生的纳米多孔块状金属的主要例子。结果表明，该材料是一种对各种氧化反应具有很高活性和选择性的Au催化剂。通过利用材料表面的官能化和各种添加剂，可以扩大和调整其催化应用。本文综述了以纳米多孔金为平台，通过添加金属、金属氧化物和分子官能团构建高性能催化材料的最新进展。
Porous bulk materials are of great interest in catalysis because they can be employed in heterogeneous gas and liquid phase catalysis, electrocatalysis, and in electrocatalytic sensing. Nanoporous gold gained considerable attraction in this context because it is the prime example of a corrosion-derived nanoporous bulk metal. The material was shown to be a very active and selective Au type catalyst for a variety of oxidation reactions. By leveraging the functionalization of the surface of the material with various additives, its catalytic applications can be extended and tuned. In this review, we will summarize recent developments in using nanoporous gold as the platform for the development of high performance catalytic materials by adding metals, metal oxides, and molecular functionalities as building blocks.
