Two-dimensional (2D) N-graphdiyne (N-GDY) nanosheets containing different number of N were synthesized by polymerization of triazine, pyrazine, and pyridine-based monomers at liquid/liquid interface. The configurations and nanostructures of N-GDY were well-characterized. The wettability changed to more hydrophilic as the N contents increased. The collected N-GDY was further employed as metal-free photocatalyst for NADH regeneration. The catalytic performance was related with the N content in the graphdiyne. The N3-GDY demonstrated the best activity. This strategy provided a new promising platform of designing unique 2D N-GDY with tunable performance in biorelated catalysis.

液/液界面制备N-Graphdiyne纳米片用于光催化NADH的再生

通过三嗪，吡嗪和吡啶基单体在液/液界面的聚合，合成了包含不同N含量的二维（2D）N-graphdiyne（N-GDY）纳米片。N-GDY的构型和纳米结构具有良好的特征。随着N含量的增加，润湿性变为亲水性。收集的N-GDY进一步用作NADH再生的无金属光催化剂。催化性能与石墨二炔中的氮含量有关。N3-GDY表现出最好的活性。该策略为设计独特的2D N-GDY提供了一个新的有前途的平台，该二维N-GDY在生物相关催化中的性能可调。
