2D metal phosphide loop‐sheet heterostructures are controllably synthesized by edge‐topological regulation, where Ni2P nanosheets are edge‐confined by the N‐doped carbon loop containing ultrafine NiFeP nanocrystals. In article number 2006860, Johnny C. Ho and co‐workers report that the loop‐sheet feature with lifted‐edges can prevent the self‐stacking of 2D nanosheets and induce accessible open channels for catalytic site exposure and charge carriers/mass transfer, resulting in a remarkable oxygen evolution activity.
