Boosting the photogenerated charge separation of g-C3N4 by constructing a Ni@Ni2P cocatalyst with a core–shell structure

The photocatalytic H 2 production rate is significantly boosted by constructing Ni@Ni 2 P core–shell cocatalyst on g-C 3 N 4 resulted from the working function gradient to improve the separation efficiency of photogenerated electrons and holes.
