dcterms:description "Graphdiyne (GDY) has been widely applied in the field of photocatalytic hydrogen production due to its unique chemical structure and excellent photoelectric performance. Herein, CuBr is used as a catalytic substrate to prepare CuBr/GDY through a cross‐coupling reaction, and a novel NENU‐5/CuBr/GDY tandem S‐scheme heterojunction photocatalyst is constructed at low temperature. The NENU‐5/CuBr/GDY heterojunction exhibits significantly enhanced activity in photocatalytic hydrogen evolution, with hydrogen evolution reaching 226.62 μmol in 5 h, which is 4.7 and 12.6 times greater than that of pure GDY and NENU‐5, respectively. Comprehensive evaluation of electrochemical, photoluminescence, and time‐resolved photoluminescence indicates that the enhanced activity of the NENU‐5/CuBr/GDY composite catalyst is attributed to high photocurrent response and low electrical resistance, which increases the efficiency of photogenerated charge separation. Additionally, density functional theory calculations and ultraviolet photoelectron spectroscopy propose the possibility of constructing the NENU‐5/CuBr/GDY tandem S‐scheme heterojunction structure. In summary, this work provides valuable ideas into tandem heterojunctions for photocatalytic hydrogen production."@de;
