Deformed One-Dimensional Covalent Organic Polymers for Enhanced CO Electroreduction to Methanol.

ABSTRACT: Spatially arranged molecular catalysts in polymeric frameworks, typically in a layered structure, are emerging strategies to mitigate the molecular aggregation and improve the catalytic performance. However, the effect of local coordination induced by polymerization remains underexplored. Here, we develop one-dimensional cobalt-tetra-amino-phthalocyanine-based covalent organic polymers (1D-COP) for the electrochemical CO reduction reaction (CORR). We use carbon nanotubes as ideal templates to induce local curvature of the 1D-COP. The COP on single-walled CNT (1D-COP/SWCNT) catalyst exhibits a maximum methanol Faradaic efficiency of 70% in an H-cell, which exceeds those on wider-diameter multiwalled carbon nanotubes (22% for 4-6 nm and 14% for 10-20 nm).
