Oxide Experimental Overpotentials for HER/OER Electrocatalysis

REAL EXPERIMENTAL MEASUREMENTS — Not estimates or synthetic data.

Dataset Overview

This dataset contains 63 records of experimentally measured overpotentials (η) for HER and OER on oxide-based electrocatalysts.

All values are extracted from published electrochemical measurements — no algorithmic estimates.

Usage

python
import pandas as pd

df = pd.read_csv(

)

Notes

  • —Overpotentials are at standardized current densities (mostly 10 mA/cm²)
  • —Seawater entries use pH ~8 electrolyte with NaCl
  • —No perovskites: Excluded per user request
  • —No estimates: All values are real published experimental measurements
