A Dataset for Electrocatalytic Hydrogen Evolution Reaction Performance of Non-noble Transition Metal Phosphides

This dataset contains 121 HER performance data points for non-noble metal based transition metal phosphide (TMPs) catalysts, covering various active metal elements (Co, Fe, Mo, Ni, W, Zn) and their combinations. Each data point contains three categories with a total of 20 feature fields: (1) preparation information (catalyst name, metal component preparation method, phosphating method, phosphating temperature, phosphate precursor); (2) Composition information (mass fractions of elements P, Ni, Co, Fe, Mo, W, Zn); (3) Performance testing information (electrode substrate used, electrolyte type, electrolyte concentration). The output variables are overpotential (mV) and Tafel slope (mV/dec) at 10 mA/cm2.
