内容記述 |
Photocatalytic production of hydrogen peroxide (H2O2) has the advantages of safety, non-polluting operation and energy savings. Molecular-designed covalent organic frameworks (COFs) are an ideal material for achieving efficient photosynthesis of H2O2. However, the current COFs photocatalyst systems have various issues. Most of them harness only ultraviolet light and a small portion of visible light, unable to utilize 52% of the infrared (IR) light in the solar spectrum. Additionally, there are drawbacks such as the need for sacrificial agents and insufficient activity for large-scale production of H2O2. In this study, H2O2 production of 7.6 μmol h−1 was achieved using IR light irradiation without a sacrificial agent, and this photocatalyst ensured 6-times H2O2 production over Pristine COFs. The apparent quantum yield (AQY) under 900 nm light was 3.2%, which is 1.2-times higher than that when using Pristine COFs. This research outcome will contribute to the development of efficient and stable organic polymer photocatalysts for IR-driven H2O2 photocatalysis. |
