Abstract

Abstract: It is a keen interest to fabricate heterojunction among semiconductors with different dimensions for improving the photocatalytic performance. Herein, the 2D/0D up‐g‐C3 N4 /Ni12 P5 heterojunctions were prepared by means of anchoring Ni12 P5 nanodots on the surface of ultrathin porous carbon nitride (up‐g‐C3 N4 ) nanosheets based on the dual control strategy of micro/nano‐ morphology and structure. The prepared 2D/0D up‐g‐C3 N4 /Ni12 P5 heterojunctions exhibit the far more outstanding photocatalytic H2 production activity in comparison with the up‐g‐C3 N4, up‐g‐C3 N4 /Pt‐3 % and u‐g‐C3 N4 /Ni12 P5 ‐3 % samples and the superior cycle stability. The prominent photocatalytic H2 production activity and stability originate from the improved visible light harvest ability and separation efficiency of charge carriers owing to the modification effect of Ni12 P5 nanodots as cocatalysts on the surface of up‐g‐C3 N4 nanosheets through forming the Ni−N bond states.
