Abstract:

Noble-metal nanoframes connected by ultrathin frames have attracted extensive attention in the field of heterogeneous catalysis due to their advantages of low loading capacity and high activity. The unique 3D open accessibility structure of the nanoframes can not only expose more active sites at the edges and vertices, improving the utilization rate of noble metal active sites, but also limit the reaction substrates to the nanoscale, increasing the chance of substrate molecules colliding. At present, researchers have proposed a variety of synthesis methods for noble-metal nanoframes, including crystal etching method, sacrificial template method, self-assembly method and so on. Their applications in catalysis and energy storage have also been explored. In this review, we summarized the synthesis strategies of noble metal nanoframes and their applications in the field of electrocatalysis in recent years, and put forward the prospect of its future development direction and challenges.

Key words: Noble metal, Nanoframes, Synthesis method, Electrocatalytic performance
