Electrochemical conversion of CO to useful products at temperatures below 100 °C is nearing the commercial scale. Pilot units for CO conversion to CO are already being tested. Units to convert CO to formic acid are projected to reach pilot scale in the next year. Further, several investigators are starting to observe industrially relevant rates of the electrochemical conversion of CO to ethanol and ethylene, with the hydrogen needed coming from water. In each case, Faradaic efficiencies of 80% or more and current densities above 200 mA cm can be reproducibly achieved. Here we describe the key advances in nanocatalysts that lead to the impressive performance, indicate where additional work is needed and provide benchmarks that others can use to compare their results.
在低于100°C的温度下将CO电化学转化为有用产品已接近商业规模。将CO转化为CO的中试装置已经在进行测试。预计将CO转化为甲酸的装置明年将达到中试规模。此外,一些研究人员开始观察到将CO电化学转化为乙醇和乙烯的工业相关速率,所需的氢气来自水。在每种情况下,都可以重复实现80%或更高的法拉第效率和高于200 mA cm的电流密度。在这里,我们描述了导致这种出色性能的纳米催化剂的关键进展,指出了还需要开展哪些额外工作,并提供了可供其他人用于比较其结果的基准。
