Carbon Shell‐Encapsulated PtFe Catalysts in High Temperature Polymer Electrolyte Membrane Fuel Cells: Balancing Molecular Sieving and Diffusion for Enhanced Reactant Access

Advanced Functional Materials, EarlyView.
Scanning electrochemical microscopy reveals reactant diffusion through porous carbon shells to PtFe cores, while the carbon‐encapsulated PtFe enables high‐performance HT‐PEMFC operation by sieving phosphate ions that induce catalyst poisoning. ABSTRACT High‐temperature polymer electrolyte membrane fuel cells (HT‐PEMFCs) operating at 160°C on phosphoric

Exploring Pb‐Chelation Chemistry in the Crystallization Dynamics of Halide Perovskites

Advanced Functional Materials, EarlyView.
A mechanism of how Pb‐chelation chemistry governs coordination geometry and initial nucleation behavior at the precursor level of halide perovskite, by regulating the deprotonation state of a chelating additive, is elucidated. This allows for innovative reaction‐system design principles that promote coherent growth while suppressing defect formation in

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...
