Electrocatalytic Reduction Of Co2

Molecular macrocycles show very promising electrocatalytic properties for the reduction of carbon dioxide. Up to now, only C1 products were produced by these catalysts. We show here that iron phthalocyanine, a commercially available molecule based on earth abundant elements, can produce light hydrocarbons upon electrocatalytic reduction of CO2 in aqueous conditions and neutral pH. When an electrochemical potential of -0.7 to -1.1 V vs. RHE is applied to a glassy carbon electrode modified with iron phthalocyanine, carbon monoxide is generated as main product. An increasing fraction of hydrogen is observed as the potential is decreased and small amounts of C1 to C4 saturated and unsaturated products are evolved. Control experiments in the absence of CO2 or catalyst does not produce any of these compounds. X-ray spectroscopic analysis of the electrode during catalysis show that the molecular catalyst remains intact and is responsible from the reaction.
