Abstract

A series of SubPcs comprising a carboxylic acid anchoring group at the peripheral (SubPcs 1, 2) or axial position (SubPc 3) were synthesized and used as sensitizers for photocatalytic H2 production, for the first time. SubPc 3/TiO2 shows the best photocatalytic activity with a hydrogen evolution rate of 1396 μmol h-1, which is much higher than that of SubPcs 1 and 2 (771 and 658 μmol g-1, respectively). This work clearly shows that considering their optical and redox properties, SubPcs are promising candidates for light-driven water splitting systems.

摘要

首次合成了一系列在周边（SubPcs 1、2）或轴向位置（SubPc 3）含有羧酸锚定基团的亚酞菁，并将其用作光催化产氢的敏化剂。SubPc 3/TiO₂表现出最佳的光催化活性，析氢速率为1396 μmol h⁻¹，远高于SubPcs 1和2（分别为771和658 μmol g⁻¹）。这项工作清楚地表明，考虑到它们的光学和氧化还原性质，亚酞菁是光驱动水分解系统的有前途的候选材料。
