The dataset related to the manuscript "Improving the lifetime of hybrid CoPc@MWCNT catalysts for selective electrochemical CO2-to-CO conversion"

In Sun et al. we demonstrated that Fe impurities in a hybrid CoPc@MWCNT catalyst lead to its performance deterioration during long-term CO2 electrolysis. Here we present the dataset the work was based on. The data are divided into four groups: (i) Current transients and gas chromatography data for short-term electrolysis at different potentials (in an excel file we give the numbers of chromatograms for each potential; current transients are given as an origin file with datasets and plots inside) (ii) Current transients and gas chromatography data for long-term electrolysis at different potentials and with different catalysts (in respective excel files we give the numbers of chromatograms; figure numbers are given in the folder names) (iii) Electron microscopy images and EDX datasets (the images and datasets are collected in the folders with respective figure numbers used in the paper) (iv) Calibration curves for ICP-MS在Sun等学者的研究中，我们证实了杂化酞菁钴@多壁碳纳米管（MWCNT）催化剂中的铁杂质会导致其在长期二氧化碳电解过程中出现性能衰减。本研究提供了该工作所依托的数据集。数据集共分为四组： (i) 不同电位下短期电解的电流瞬变与气相色谱数据：Excel文件中给出了各电位对应的色谱图编号；电流瞬变数据以Origin文件格式存储，内含数据集与绘图结果 (ii) 不同电位、不同催化剂条件下长期电解的电流瞬变与气相色谱数据：对应Excel文件中给出了色谱图编号；图表编号标注于各文件夹的名称中 (iii) 电子显微镜图像与能量色散X射线能谱（EDX）数据集：图像与数据集收纳于标注有论文对应图表编号的文件夹内 (iv) 电感耦合等离子体质谱（ICP-MS）校准曲线
