Abstract:

Hydrogen peroxide (H2O2) is a versatile and environmentally friendly oxidizer widely used in diverse fields. The solar-driven photocatalytic oxygen reduction reaction generates H2O2 from air and water, avoiding undesirable byproducts. This green and pollution-free route is applicable to various domains. Although extensive research covers covalent organic framework (COF)-based photocatalysts for H2O2, little attention has been paid to systems that generate high-value chemicals in the presence of scavengers. To address this gap, we systematically discuss the simultaneous photocatalytic generation of H2O2 and valuable chemicals. We emphasize the pathways for H2O2 generation using COF-based photocatalysts and highlight the role of sacrificial agents. Novel synthetic methodologies and modification strategies for enhancing the photocatalytic yield are presented. Our work aims to strengthen the identification and discussion of the challenges faced by photocatalysts in this field. This study aims to inspire further investigations and innovations in COF-based photocatalysis for sustainable and value-added chemical synthesis by presenting a holistic view.
