Data underlying the publication: Interrogation of oxidative pulsed methods for the stabilization of copper electrodes for CO2 electrolysis

Data sets containing the data points used for creating figures in both the manuscript and supporting information. Raw Data sets taken from gas chromatography, potentiostat and in situ Raman spectroscopy setup.The gas chromatography data is converted into faradaic efficiencies (FE) as a function of time. Potentiostat data contains current or potential values as supplied to the electrolyser as a function of time. In situ Raman contains the measured response as a function of wavenumber.<br>FE profiles are used to study the effect of 'off' time on the lifetime of the copper catalyst. Potential data is used to study the anodic polarization curve of the copper electrode in 1 M KHCO3. Raman data was utilised to confirm the 'off' time dependency for the formation of cuprite.<br>

本数据集包含用于制作手稿及辅助材料中所有图表的数据点。原始数据集采集自气相色谱（gas chromatography）、恒电位仪（potentiostat）及原位拉曼光谱（in situ Raman spectroscopy）装置。其中，气相色谱数据被转换为随时间变化的法拉第效率（faradaic efficiencies, FE）；恒电位仪数据包含施加于电解槽（electrolyser）的随时间变化的电流或电位值；原位拉曼数据则包含随波数（wavenumber）变化的实测响应信号。
法拉第效率曲线被用于探究“断电”时长对铜催化剂寿命的影响；电位数据被用于研究1 M碳酸氢钾（KHCO3）电解液中铜电极的阳极极化曲线（anodic polarization curve）特性；拉曼数据被用于验证氧化亚铜（cuprite）的生成与“断电”时长的相关性。
