Oxygen vacancy-rich hierarchical NiFe LDH microtubes with excellent intrinsic conductivity and stability exhibit fantastic OER activity.
The two‐dimensional lamellar materials disperse platinum sites and minimize noble‐metal usage for fuel cells, while mass transport resistance at the stacked layers spurs device failure with a significant performance decline in membrane electrode assembly (MEA). Herein, we implant porous rigid sulfonated covalent organic frameworks (COF) into graphene‐based catalytic layer construction of steric mass‐charge channels, which highly facilitates activity oxygen reduction reactions both rotating...
