Abstract

Hydrogen peroxide (H 2 O 2 ) is a crucial chemical with widespread applications in our daily lives and as an energy material. Recently, the generation of H 2 O 2 using light energy has garnered significant attention for its potential contribution to a sustainable society. In particular, near-infrared region (NIR) light-driven H 2 O 2 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 H 2 O 2 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 H 2 O 2 under 1000 nm NIR light irradiation.
