Carbon dioxide accounts for over 80 percent of all greenhouse gas emissions. For many, carbon dioxide emissions account for significant environmental issues, but for researchers like Haotian Wang of Harvard University, carbon dioxide could be the perfect raw material.

According to a new study, Wang and his team are well on the way to developing a system that uses renewable electricity to electrochemically transform carbon dioxide into carbon monoxide. The carbon monoxide could then be used in a host of industrial processes, such as plastics production, creating hydrocarbon products, or as a fuel itself.

This from Harvard University:

The energy conversion efficiency from sunlight to CO can be as high as 12.7%, more than one order of magnitude higher than natural photosynthesis.

An important innovation is the optimized interface between gas, fluid and copper particles, allowing the very efficient supply of CO2 and removal of the product, CO.

In an effort to convert carbon dioxide into carbon dioxide, researchers have developed an electrode in the form of a hollow porous coper fiber that completes this transformation at an extremely efficient level.

The researchers, including ECS member Marc T.M. Koper, believe that this development could give the industrial industry an edge, where it would be extremely beneficial for chemical processes that require gas conversion.

The process is not confined to the conversion of carbon dioxide to carbon monoxide, however. Because the manufacturing method is suited for other fibers, it could also be applied to the conversion of oxygen in a fuel cell or hydrogen conversion in the electrochemical production of ammonia.

While the principal idea behind the process is straightforward, the efficiency and selectivity of the reaction is the surprising factor.
