Robust Covalent Organic Frameworks for Photosynthesis of HO: Advancements, Challenges and Strategies.

Since 2020, covalent organic frameworks (COFs) are emerging as robust catalysts for the photosynthesis of hydrogen peroxide (HO), benefiting from their distinct advantages. However, the current efficiency of HO production and solar-to-chemical energy conversion efficiency (SCC) remain suboptimal due to various constraints in the reaction mechanism. Therefore, there is an imperative to propose efficiency improvement strategies to accelerate the development of this reaction system.

Electronic Structure Modulation of Oxygen-Enriched Defective CdS for Efficient Photocatalytic HO Production.

Artificial photosynthesis for hydrogen peroxide (HO) presents a sustainable and environmentally friendly approach to generate clean fuel and chemicals. However, the catalytic activity is hindered by challenges such as severe charge recombination, insufficient active sites, and poor selectivity. Here, a robust strategy is proposed to regulate the electronic structure of catalyst by the collaborative effect of defect engineering and dopant.
