In electrochemical processes, an input of electrical energy drives CO 2 conversion reactions in an electrolytic cell in which CO 2 is reduced on the cathode while oxygen evolves at the anode. CO 2 can be converted to a range of fuels and fuel precursors by this means, including CO, formic acid (HCOOH), methane (CH 4 ), and ethylene (C 2 H 4 ).
