A facile synthetic route for highly durable mesoporous platinum thin film electrocatalysts based on graphene: morphological and support effects on the oxygen reduction reaction

摘要: Porous-structured noble metal electrocatalysts offer activity and durability benefits based on a high surface area interconnected nanostructure, respectively. However, conventional technical methods used for synthesizing porous structure are still difficult as well resulting in defects the structure. Here we report facile route synthesis of uniform, large-area mesoporous platinum thin films ionic polymer doped graphene, which exhibit substantially enhanced oxygen reduction relative to commercial Pt/C. Notably, remarkable (≥95% retention electrochemical activities after 30 000 cycles intensive accelerated tests) is acquired ascribed synergistic effects derived from Pt (morphology) polymer-doped graphene (support). The suggested robust concept controlled mesoporous-structured film could be great breakthrough obtaining highly durable electrocatalyst.
