Boron-doped CuO nanobundles for electroreduction of carbon dioxide to ethylene.

Novel boron-doped CuO nanobundles are designed for CO2 reduction to the single multi-carbon product of ethylene, and their faradaic efficiency can reach 58.4% with a current density of 18.2 mA cm−2. This active, selective and simply prepared electrocatalyst provides a promising electrocatalyst candidate for CO2 reduction to ethylene. [ABSTRACT FROM AUTHOR]
