COF-Based Photocatalysts for Enhanced Synthesis of Hydrogen Peroxide.

Covalent Organic Frameworks (COFs), with their intrinsic structural regularity and modifiable chemical functionality, have burgeoned as a pivotal material in the realm of photocatalytic hydrogen peroxide (HO) synthesis. This article reviews the recent advancements and multifaceted approaches employed in using the unique properties of COFs for high-efficient photocatalytic HO production. We first introduced COFs and their advantages in the photocatalytic synthesis of HO. Subsequently, we spotlight the principles and evaluation of photocatalytic HO generation, followed by various strategies for the incorporation of active sites aiming to optimize the separation and transfer of photoinduced charge carriers. Finally, we explore the challenges and future prospects, emphasizing the necessity for a deeper mechanistic understanding and the development of scalable and economically viable COF-based photocatalysts for sustainable HO production.
