Durable Proton Exchange Membrane Based on Polymers of Intrinsic Microporosity for Fuel Cells
A novel composite proton exchange membrane (PEM) design that leverages carboxylic acid‐functionalized polymers of intrinsic microporosity (cPIM‐1) and polyvinylpyrrolidone (PVP). Harnessing Lewis acid‐base interactions enables the development of a synergistic microporous structure that confines phosphoric acid clusters, enhancing proton conductivity ...

Surface Engineering of PtSe2 Crystal for Highly Efficient Electrocatalytic Ethanol Oxidation
2D PtSe2 has been demonstrated as high‐performance catalyst for electrocatalytic ethanol oxidation. Plasma treatment engineers the surface of single‐crystalline PtSe2 by removing Se atoms, resulting in the exposure of PtSe2 (101) facet. Excellent EOR activity and poison‐resistance are demonstrated, which is rationalized by in situ electrical transport ...

Decoding Directional Control in Metal‐Assisted Chemical Etching via Catalyst Architecture
Metal‐assisted chemical etching (MaCE) enables silicon nanostructure fabrication but suffers from isotropic undercutting. This study highlights the critical role of catalyst morphology in etching directionality. High‐aspect‐ratio catalysts induce lateral etching, while thermal treatment at 450 °C stabilizes catalyst geometry, promoting vertical etching.

In nitrogen vacancies‐rich nickel nitride (Ni3N‐VN), a local microenvironment of nitrogen vacancies and adjacent Ni sites is formed. The electron‐rich Ni‐sites can be converted to NiOOH at a lower potential, and urea adsorption on the electron‐deficient nitrogen vacancy region is conducive to its partial dissociation, conceiving to efficient urea ...
