AI Technical Summary
Existing technologies make it difficult to synthesize atomically uniform and structurally complete ZnNiCoCuMn high-entropy MOF-74 materials under mechanical ball milling conditions, and their multi-metal synergistic catalytic potential in the oxygen evolution reaction of water electrolysis has not been fully explored.
A mechanical ball milling method was adopted to initiate a mechanochemical reaction through high-energy ball milling, enabling the metal salt to coordinate with the organic ligand in situ, thereby overcoming the coordination energy barrier between metal ions and synthesizing high-entropy ZnNiCoCuMn MOF-74 electrocatalytic material.
A uniformly distributed high-entropy solid solution structure was obtained, exhibiting excellent catalytic activity and long-term stability for the oxygen evolution reaction, with an overpotential lower than that of traditional methods.
