Abstract:

Exploring non-precious metal catalysts to replace precious metals in energy related catalysis, such as oxygen activation and water splitting has become one important hotspot in both fundamental research and industrial applications. However, one of the biggest issues currently restricting the application of non-precious metal catalysts is their low stability compared with precious metal catalysts. Especially when suffering from harsh conditions such as strong acids, alkalis, or high overpotential, they are susceptibly corroded or over-oxidized, subsequently leading to badly inactivation. Therefore, it urgently demands new catalytic materials and concepts to solve this issue. Herein, we will present our recent progress on how to improve the stability of non-precious catalysts in harsh conditions. The report will focus on two examples. The first example is about the concept “Chainmail for catalysis” with 2D materials as the chainmail, and the second is about the 2D materials confining single atom metal catalysts. These studies provide efficient ways for rational design of non-precious metal catalysts with high activity and stability in conversion of energy small molecules.
