High-Throughput SECCM and EDX Data for the Hydrogen Evolution Reaction in Ag-Au-Pd-Pt-Ru and Ag-Au-Pd-Pt-Rh Thin-Film Materials Libraries

This dataset contains high-throughput energy-dispersive X-ray spectroscopy (EDX) data and scanning electrochemical cell microscopy (SECCM) results for two thin-film materials libraries (Ag-Au-Pd-Pt-Ru and Ag-Au-Pd-Pt-Rh) investigated for the hydrogen evolution reaction (HER) in alkaline conditions. The thin films were fabricated via magnetron sputtering, and their composition and electrochemical activity were assessed at 342 distinct measurement areas per library. The dataset provides a correlation between composition and HER activity, offering valuable insights into the electrocatalytic performance of these multimetallic systems.
