Lowering platinum (Pt) loadings without sacrificing power density and durability in fuel cells is highly desired yet challenging because of the high mass transport resistance near catalyst surfaces. We tailored three-phase microenvironment by optimizing ionomer incorporating ionic covalent organic framework (COF) nanosheets into Nafion. The mesoporous apertures 2.8 to 4.1 nanometers appendant sulfonate groups enabled proton transfer promoted oxygen permeation. activity Pt peak cell with...
The development of new reaction chemistry is highly desirable to construct structural and functional covalent organic frameworks (COFs). Benefiting from the extremely large database metal-catalyzed database, we herein develop a synthetic strategy that can generate quinoline-linked COFs via silver-catalyzed three-component one-pot achieve functionalization by simple replacement alcohols. This approach construction robust COF structures characterized extended π-conjugation holds potential pave...
