Understanding carbon dioxide activation and carbon–carbon coupling over nickel

I ran across this interesting article while searching for others, and it's open access:

Understanding carbon dioxide activation and carbon–carbon coupling over nickel

This might be a good use of surplus energy from wind as solar, and a means of usable storage. Conversion of atmospheric or power plant CO2, sequestering it, is a proper step in our technological development, and may help appease the religious AGW zealots.

Here is one on CO2 to ethanol conversion, though it isn't open access:

Cooperative CO2-to-ethanol conversion via enriched intermediates at molecule–metal catalyst interfaces; here is a snippet:

We further integrated the CO2 reduction and H2O oxidation reactions in a system employing a membrane electrode assembly (MEA; Supplementary Fig. 15) to carry out the full electrosynthesis of ethanol from CO2 and water via the reaction:

2CO2+3H2O→C2H5OH+3O2Eo=1.14
(1)

We operated the system for an initial 12 h at a full-cell voltage of 3.7 V. The system delivered a stable current of 0.6 A and an average ethanol FE of 41% (Fig. 3e). Thus, we obtained a full-cell EE (see Methods for calculation details) of 13%. This value is reported without the benefit of ohmic resistance (iR) corrections.​

Worth thinking about.

Worth thinking about.

Yes, it is at least a scientific advancement that might become reality.

While interesting, ethanol has some problems as a fuel, mostly that it is hygroscopic.
