Regulating Substituents in Coplanar 2D Ladder Polymers for Enhanced Photocatalytic Production of H2O2
Photocatalytic hydrogen peroxide (H2O2) production using conjugated polymers as photocatalysts is a green and sustainable approach to synthesizing H2O2. Nevertheless, the efficiency is still hindered by the inefficient charge separation and transfer dynamics. Herein, a series of coplanar 2D ladder polymers with different substituents were reported as metal-free photocatalysts for artificial photosynthesis of H2O2. Detailed experimental and theoretical investigations reveal that the coplanar 2D skeleton and strong electron-withdrawing substituents could profoundly facilitate charge separation and transfer. Possessing these notable merits, the cyano-substituted polymer (PAE-CN) exhibits remarkable photocatalytic performance on H2O2 evolution. This study contributes to the development of effective polymer photocatalysts tailored for potential applications in artificial photosynthesis.
期刊介绍：
ACS Applied Polymer Materials is an interdisciplinary journal publishing original research covering all aspects of engineering, chemistry, physics, and biology relevant to applications of polymers.
The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates fundamental knowledge in the areas of materials, engineering, physics, bioscience, polymer science and chemistry into important polymer applications. The journal is specifically interested in work that addresses relationships among structure, processing, morphology, chemistry, properties, and function as well as work that provide insights into mechanisms critical to the performance of the polymer for applications.
