Efficient photoelectrocatalytic CO2 reduction to CH3OH via porous g-C3N4 nanosheets modified with cobalt phthalocyanine in ionic liquids

Photocatalytic CO 2 reduction into fuels is desirable; however, realizing efficient C n H 2 n +1 OH ( n = 1, 2) synthesis that involves multielectron-coupled proton transfer alongside C–C bond formation remains a challenge.
