摘要

光催化制氢对能源和经济的可持续发展具有重要意义。共价有机框架（COFs）在光催化方面的应用受到了广泛的关注。本文通过Povarov反应将亚胺键转化为喹啉环，合成了结晶OH-COFs。TiO2-COF在水/醇体系中表现出优异的光催化产氢性能。该策略为基于cof -无机半导体杂化的高效光催化剂的设计和合成提供了可行的方法。

TiO2-anchored three-dimensional integration of layer covalent organic framework for photocatalytic H2 production

Photocatalytic H₂ production presents great significance for sustainable development of energy and economy. Covalent organic frameworks (COFs) have received huge attention in photocatalytic applications. Herein, crystalline OH-COFs were synthesized through the transformation of imine bond to quinoline ring via Povarov reaction. TiO₂-COF exhibited excellent photocatalytic performance for H₂ production in H₂O/alcohol system. This strategy provides available method for the design and synthesis of highly efficient photocatalysts based on COF-inorganic semiconductor hybridization.

期刊介绍： Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications. Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
