The potential of a graphene supported porous organic polymer (POP) for CO2 electrocatalytic reduction.
A one pot, bottom up assembly of a pyrimidine containing porous organic polymer (PyPOP) was conducted to homogenously deposit the PyPOP atop unmodified graphene sheets, affording a composite material PyPOP@G. The PyPOP demonstrated an appreciable affinity toward CO2 capture but was found to be largely insulating, hindering its usage in potential electrochemical conversion of CO2. However, its composite with graphene was found to be microporous, with maintained affinity toward CO2 and furthermore demonstrated significant electrochemical activity toward CO2 reduction (5 mA cm 2 at 1.6 V) not observed in either of its two components separately.
