Abstract: Hydrogen peroxide (H2O2) is a versatile and environmentally friendly oxidizer widely used in diverse fields. The solar-driven photocatalytic oxygen reduction reaction (ORR) generates H2O2 from air and water, avoiding undesirable by-products. This green and pollution-free route is applicable across various domains. While existing research extensively covers covalent organic framework (COF) based photocatalysts for H2O2, little attention is given to systems generating high-value chemicals with scavengers. To address this gap, we systematically discuss photocatalysis generating H2O2 and valuable chemicals, simultaneously. We emphasize pathways for H2O2 generation using COF-based photocatalysts, highlighting the role of sacrificial agents. Novel synthetic methodologies and modification strategies to enhance photocatalytic yield are presented. Our contribution extends to identifying and discussing challenges faced by photocatalysts in this area. This work aims to inspire further investigations and innovations in COF-based photocatalysis for sustainable and value-added chemical synthesis by presenting a holistic view.
