AbstractThe high concentrations of CO2 in industrial flue gases make these point sources attractive candidates for renewably powered electrocatalytic conversion of CO2 to products. However, trace SO2 in common flue gases rapidly and irreversibly poisons catalysts. Here we report that limiting hydrogen adsorption in the vicinity of electrochemically active sites deactivates SO2 to enable efficient CO2 conversion.

AbstractElectrochemical reduction of carbon monoxide is a promising carbonate-free approach to produce ethylene using renewable electricity. However, the performance of this process suffers from low selectivity and energy efficiency. A priority has been to weaken water dissociation with the aim of inhibiting the competing hydrogen evolution reaction but when this path was examined by replacing H2O with D2O, a further-reduced selectivity toward ethylene was observed.

AbstractAcidic electrochemical CO2 reduction (CO2R) addresses CO2 loss and thus mitigates the energy penalties associated with CO2 recovery; however, acidic CO2R suffers low selectivity. One promising remedy—using a high concentration of alkali cations—steers CO2R towards multi-carbon (C2+) products, but these same alkali cations result in salt formation, limiting operating stability to <15 h.

Preparation of electrodesThe electrodes were prepared by air-bushing the CuPc/CNP or EDTA/CuPc/CNP inks onto hydrophobic carbon papers. The spray density was kept at 0.1 mL cm-2. The CuPc/CNP catalyst inks were prepared by dispersing 64 mg CuPc ( > 99.5%, Sigma-Aldrich) and 42 mg CNP (Vulcan XC 72, Fuel Cell Store) mixture in 30 mL methanol (>99.5%, Fisher chemical) with 150 µL 5 wt% PiperIon (Fuel Cell Store) anion exchange ionomer as the binder.
