Data used for publication: Broad topic: electrochemical reduction of CO2 using gas diffusion electrodes and neutral electrolyte Data is devided in subfolders named after the figure of the paper. Raw data, processed data, and Origin/Power Point files are all contained in the subfolders A subfolder corresponding to a sample contains: data from a potentiostat, gas and liquid chromatograms, recording of flow, pressure and temperature, tables of calculated Faradaic efficiency (FE), png image of the FE vs t, zipped raw files. .json file was created using a yadg scheme (https://dgbowl.github.io/yadg/master/index.html), and data was processed by a dgpost scheme (https://dgbowl.github.io/dgpost/master/index.html)
