    摘要 中英对照阅读

    TpBd-COFs with different morphologies were synthesized by regulating the dynamic equilibrium of imine bonds using acetic acid as a modulator. The TpBd-COF nanosheet exhibits a higher photocatalytic H2 evolution activity than the TpBd-COF nanowires due to the enhanced light-harvesting ability, optimized energy levels and facilitated electron transfer.

    Keywords:beta-ketoenamine; covalent organic frameworks

    通过使用醋酸作为调节剂来调节亚胺键的动力学平衡,合成了具有不同形态的TpBd-COFs。由于提高了光捕获能力、优化了能级和促进了电子转移,TpBd-COF纳米片表现出比TpBd-COF纳米线更高的光催化氢气生成活性。
