Carbon Dioxide

With atmospheric greenhouse gas levels at their highest in history, many researchers have been contemplating one question: How can we reutilize carbon dioxide?

One new study reports a new catalyst with the ability to execute highly selective conversion of carbon dioxide into ethylene, producing an important source material for the chemical industry.

The push to convert carbon dioxide into useful chemicals is not a completely novel concept among the scientific community. For this study, researchers opted to make the process more efficient by implementing a new catalyst with higher selectivity to produce more useful chemicals and less unwanted byproducts.

Ruhr-Universitӓt Bochum PhD student and ECS student member, Hemma Mistry, veered away from the traditional catalyst used in this process and instead opted for copper films treated with oxygen or hydrogen plasmas. By doing this, Mistry was able to alter surface properties for optimal performance.
