In Situ Surface Reconstruction of Catalysts for Enhanced Hydrogen Evolution

The in situ surface reconstitution of a catalyst for hydrogen evolution refers to its structure induced by strong interactions with reaction intermediates during the (HER), which eventually leads self-optimization active sites. In consideration superior performance that can be achieved reconstitution, more and attention has been paid relationship between site HER activity. More and/or operando techniques have explored track dynamic structural catalysts order clarify underlying mechanism. This review summarizes recent advances various types reconstruction such as reconfiguration crystallinity, morphological evolution, chemical composition phase transition refactoring, defects, interface refactoring process. Finally, different perspectives outlooks are offered guide future investigations. is expected provide some new clues deeper understanding reactions targeted design desirable structures.
