Near-Infrared Light-Driven H<sub>2</sub>O<sub>2</sub> Generation via Metalloporphyrin-Based Covalent Organic Frameworks and Nanodisks
Hydrogen peroxide (H2O2) is a crucial chemical with widespread applications in our daily lives and as an energy material. Recently, the generation of H2O2 using light energy has garnered significant attention for its potential contribution to a sustainable society. In particular, near-infrared region (NIR) light-driven H2O2 generation holds great promise for solar energy utilization. However, due to the low energy of NIR light, developing an NIR-driven photocatalyst remains a challenge. In this study, we demonstrate that nickel-coordinated porphyrin-based covalent organic frameworks (COFs) can efficiently generate H2O2 under NIR light irradiation (700–800 nm). Additionally, the efficiency was improved (7.0-hold) by covalent organic nanodisks (CONs) exfoliated from the COFs stacking structure. Furthermore, the CONs were able to generate H2O2 under 1000 nm NIR light irradiation.
