Citat: "...
Researchers have developed a highly selective catalyst capable of
electrochemically converting carbon dioxide -- a greenhouse gas -- to
carbon monoxide with 92 percent efficiency. The carbon monoxide then can
be used to develop useful chemicals.
...
The resulting carbon monoxide, he continued, can be used as an industry
feedstock for producing synthetic fuels, while reducing industrial
carbon dioxide emissions by as much as 40 percent.
...
Reducing greenhouse carbon dioxide emissions from fossil fuel use is
considered critical for human society. Over the last 20 years,
electrocatalytic carbon dioxide reduction has attracted attention
because of the ability to use electricity from renewable energy sources
such as wind, solar and wave.
