Combined effect of P/N co-doping in hollow carbon nanospheres for electrocatalytic alkaline hydrogen evolution

In the data confluence of this article, the XRD test data consists of the original file format, exported data in txt format, drawing Orign plots, and finally the final picture; the nitrogen adsorption test data consists of the original SMP file---exported data in txt format---plotting Orign plots----the final picture; the SEM or TEM data consists of the photographed original picture---exported pictures; XRD data are composed of the most original files raw---- exported data in txt format---drawing Orign plots, and the final pictures; electrochemical data are composed of the most original files cex or CV, EIS data---exported data in txt format---drawing Orign plots, and the final pictures.The tabular data in this paper are mainly in the “Supporting Information” folder and correspond to the additional data for the text and the plots. The row and column headings correspond to the P/N-HCN-n-T series catalysts and their required data in the main text, and the units of measurement are in the International System of Units (SI), e.g., BET Surface Area (m2/g), Total Pore Volume (m3/g), Overpotential (V), Tafel slope (mV dec-1), Rct (Ω), and so on.
