Selective electrochemical reduction of CO<inf>2</inf> to CO with a cobalt chlorin complex adsorbed on multi-walled carbon nanotubes in water

Abstract

Electrocatalytic reduction of CO<inf>2</inf> occurred efficiently using a glassy carbon electrode modified with a cobalt(ii) chlorin complex adsorbed on multi-walled carbon nanotubes at an applied potential of -1.1 V vs. NHE to yield CO with a Faradaic efficiency of 89% with hydrogen production accounting for the remaining 11% at pH 4.6.
