Parallel experiments in electrochemical CO2 reduction enabled by standardized analytics

Electrochemical CO 2 reduction (eCO 2 R) is a promising strategy to transform detrimental CO 2 emissions into sustainable fuels and chemicals. Key requirements for advancing this field are the development of analytical systems and of methods that are able to accurately and reproducibly assess the performance of catalysts, electrodes and electrolysers. Here we present a comprehensive analytical system for eCO 2 R based on commercial hardware, which captures data for >20 gas and liquid products with
