Assesses how nickel foam structure affects reproducibility of oxygen evolution reaction outcomes in electrochemical experiments, indicating the need for standardization.
Nickel (Ni) foam-based electrodes are excellent catalysts for the oxygen evolution reaction; however, we found that the random pore-size distribution of Ni foams contributes to a significant variability in electrochemically active surface area, compromising experimental reproducibility. We provide insights into quantifying this critical material property, verified by four electrochemical laboratories.
