Cobalt-phthalocyanine-modified two-dimensional cobalt hydroxide complexes for highly selective electrocatalytic reduction of CO2to CO

We have synthesized CoPc/α-Co(OH) 2 catalysts for CO 2 electroreduction to CO with a faradaic efficiency of 98.4%. The excellent catalytic performance could be mainly attributed to the strong interaction between CoPc molecules and α-Co(OH) 2 support.
