Energy‐Enhanced Aqueous Organic Flow Batteries Enabled by Integrated Proton‐Coupled Electron Transfer‐Induced Carbon Capture and Utilization

Advanced Energy Materials, EarlyView.
This work presents an aqueous organic flow battery that integrates energy storage with carbon capture and utilization. By feeding flue gas into an oxygen‐tolerant FFDS posolyte, reversible CO2 capture, utilization, and release is achieved via PCET‐driven pH swings.

Two‐Dimensional Polymers as Modular Metal‐Free Solid‐State Catalysts for Efficient Sono‐Piezo‐Photocatalytic Hydrogen Peroxide Production

Angewandte Chemie International Edition, EarlyView.
This study demonstrates the high piezo‐photocatalytic activity of solid molecular catalysts (SMCs) in the production of hydrogen peroxide from water and oxygen. Through the rational design of molecular motifs (diphenylpyridine or terpyridine) and backbone functionalities (methyl group, aliphatic amine antenna, or aromatic pyrrole unit), as well as ...
