High Free‐Volume Imidazole‐Based Ionomers for High‐Temperature Proton Exchange Membrane Fuel Cells
Advanced Science, EarlyView.High free‐volume imidazole‐based ionomers (PF4IM‐72) enable enhanced phosphoric acid uptake and efficient proton transport, delivering peak power densities of 0.645 W cm−2 at 160 °C and 0.838 W cm−2 at 200 °C in HT‐PEMFCs. This work highlights a promising platform for next‐generation ionomers with improved high‐temperature performance and stability ...

Microenvironment Engineering as a Design Principle for Suppressing Catalyst Metal Loss
Angewandte Chemie, EarlyView.Under ionomer‐containing microenvironments, nonporous carbon supports enhance the retention of dissolved platinum ions, whereas porous carbon supports promote pore‐confined redeposition and mitigate net platinum loss. ABSTRACT Stability losses in platinum electrocatalysts arise from dissolution, redeposition, and restructuring processes that are ...

Advanced Science, EarlyView.A dynamic reconstruction strategy was utilized to construct PtCu/Cu3P heterostructures on the surface of self‐supporting Cu3P nanowires. The loose porosity in the restructured layer, together with a dynamic “dissolution‐redeposition” equilibrium during electrocatalysis, enables the electrode to maintain a low, stable overpotential for 240 h at ampere ...

Angewandte Chemie, EarlyView.We report a functionalization‐mediated strategy to synthesize robust iron (Fe) atoms selectively coordinated at bridge sites on molybdenum disulfide (MoS2) nanosheets. The resulting b‐Fe‐MoS2 catalyst exhibits enhanced activity and durability for the hydrogen evolution reaction in proton exchange membrane water electrolyzers compared to atop ...

Angewandte Chemie, EarlyView.Using defect‐rich Co‐N2O2 single‐atom catalysts as a model system, this work reveals that atomic site density governs the competition between H2O2 electrosynthesis and microenvironmental decomposition during 2e−‐ORR. Optimised site isolation suppresses HPRR and HDR, thereby establishing a site‐density principle to balance H2O2 formation and ...
