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.
二维（2D）氮杂石墨炔（N-GDY）纳米片通过在液/液界面聚合三嗪、吡嗪和吡啶基单体合成，具有不同数量的氮。N-GDY 的结构和纳米结构得到了很好的表征。随着氮含量的增加，润湿性变为更亲水。收集的 N-GDY 进一步用作无金属光催化剂用于 NADH 再生。催化性能与石墨炔中的氮含量有关。N3-GDY 表现出最佳的活性。该策略为设计具有生物相关催化中可调性能的独特二维 N-GDY 提供了一个新的有前途的平台。
