The catalytic, electrocatalytic, or photocatalytic conversion of CO2 into useful chemicals in high yield for industrial applications has so far proven difficult. Herein, we present our work on the electrochemical reduction of CO2 in seawater using a boron-doped diamond (BDD) electrode under ambient conditions to produce formaldehyde. This method overcomes the usual limitation of the low yield of higher-order products, and also reduces the generation of H2 . In comparison with other electrode materials, BDD electrodes have a wide potential window and high electrochemical stability, and, moreover, exhibit very high Faradaic efficiency (74%) for the production of formaldehyde, using either methanol, aqueous NaCl, or seawater as the electrolyte. The high Faradaic efficiency is attributed to the sp(3)-bonded carbon of the BDD. Our results have wide ranging implications for the efficient and cost-effective conversion of CO2.read more

Electrocatalytic CO2 conversion to oxalate by a copper complex.
TL;DR: A dinuclear Copper(I) complex that is oxidized in air by CO2 rather than O2 is described; the product is a tetranuclear copper(II) complex containing two bridging CO2-derived oxalate groups, which can be nearly quantitatively electrochemically reduced at a relatively accessible potential, regenerating the initial dinuclear copper (I) compound.
