Abstract: Amorphous‐like Ni–Fe–S ultrathin nanosheets by oxygen incorporation and electrochemical tuning show excellent OER activity at high current densities. Such excellent performance could be attributed to the unique 3D porous configuration composed of amorphous‐like ultrathin nanosheets… read more here.
