OCx24 Dataset

This dataset contains electrochemical performance data for metal alloy catalysts tested for CO₂ reduction and hydrogen evolution reactions. The samples were synthesized using two different methods:

Chemical Reduction: Produces powder catalysts
Spark Ablation: Produces porous film catalysts

All catalysts were applied to Gas Diffusion Electrodes (GDEs) and tested in Membrane Electrode Assemblies (MEAs) in neutral conditions using 0.1M KHCO₃ electrolyte. The electrochemical testing was performed in a two-electrode configuration with direct voltage measurement. Gas products were analyzed using Gas Chromatography (GC).

Each synthesis method includes three duplicate samples for statistical reliability. All samples contain X-ray Fluorescence (XRF) composition data, and most samples include X-ray Diffraction (XRD) structural characterization data.

1. Combine multiple samples with the same composition into single data points.

Filter Instructions:
• Use "Reset" to clear all filters and show all data
• Export filtered data as CSV using the export button
• You can aggregate by either target composition or xrf composition, but not both at the same time.

Filter Options:
• UofT/VSP: Individual synthesis methods
• Both (XRF compositions): Samples with same measured XRF composition in both UofT and VSP
• Both (Nominal compositions): Samples with same nominal composition in both UofT and VSP
• Either (UofT or VSP, All): All samples regardless of synthesis method
