Harmonizing the Pyrene and Ether Groups in Covalent Triazine Polymers for Highly Effective H2O2 Photosynthesis via One‐Step Two‐Electron Oxygen Reduction

open access: yesAdvanced Functional Materials, EarlyView.
The pyrene and ether groups are incorporated into the covalent triazine polymer (CTP) structure. The synergistic effect of the two functional groups endows CTP with better electron transfer, light absorption, and oxygen activation properties. An impressive apparent quantum yield (13.2% @420 nm) and a remarkable solar‐to‐chemical conversion efficiency ...

Design of Efficient and Mechanically Robust Anion Exchange Membrane for Water Electrolysis Achieved by Chemically Crosslinked Elastomers using Polyfluorene‐Based Conjugated Polymers

open access: yesAdvanced Functional Materials, EarlyView.
High‐performance SEBS‐PFB AEM is developed by crosslinking SEBS‐amine with polyfluorene‐based crosslinker containing benzene spacer. With the superior electrochemical and mechanical properties, SEBS‐PFB enabled an AEMWE single cell to achieve a high current density of 14.0 A cm−2 at 2.0 V and 80 °C in 1 m KOH, using a PtRu/C cathode and Ni2Fe anode ...

An In Situ Study of the Topochemical Transformation of Hybrid Layered Hydroxides Into Metallic Nanocomposites

open access: yesAdvanced Functional Materials, EarlyView.
Herein, the topochemical transformation of cobalt‐based layered hydroxides into nanocomposites is investigated using advanced real‐time characterization techniques combined with thermogravimetric analysis. The study reveals how interlayer carboxylic acids direct the transformation pathway, highlighting the role of carbon content and anion length. These
