 This research has developed a new type of catalyst that can reduce carbon dioxide, CO2, efficiently. The catalyst consists of a nickel atom surrounded by two nitrogens, which allows it to be more selective in reducing CO2 than other catalysts. The catalyst also has high activity and a high faradaic efficiency of carbon monoxide, CO, meaning that it converts CO2 into CO quickly and efficiently. Furthermore, the catalyst's performance remains stable across a wide range of voltages, making it suitable for use in real-world applications.
