New catalyst can help turn carbon dioxide into plastic

Scientists have created a catalyst that can efficiently convert carbon dioxide to ethylene, which is used to produce the most common type of plastic.
At the heart of this work is the carbon dioxide reduction reaction, wherein CO2 is converted into other chemicals through the use of an electrical current and a chemical reaction, aided by a catalyst.
Many metals can serve as catalysts in this type of reaction gold, silver and zinc can make carbon monoxide, while tin and paladium can make formate. Only copper can produce ethylene, the core component of polyethylene plastic.
