The hangman structure plays a critical role in determining the reaction rates of molecular CO2 electrocatalysis through constructing pendant functional groups secondary coordination spheres metal active sites. However, achieving structures commonly requires complicated asymmetric synthesis. It is necessary to search for simple alternative strategies develop with realization concept green chemistry. In this work, we report synthesis electrocatalysts based on noncovalent π–π interaction between cobalt (Co) phthalocyanine nanotubes and 1-aminopyrene. promoted kinetics interfacial inner outer sphere electron transfer complex chemisorption *COOH *CO species both Co sites amine bridge geometry. resultant afforded very high turnover frequency 4.37 s–1 at an overpotential 0.29 V electrochemical CO conversion thus industrial interest current density being steady 350 mA cm–2.
