The comparisons of a LSVs, b overpotentials at various current densities, c Tafel slopes, and d stability with the controls in OER. The comparisons of e LSVs, f overpotentials at various current densities, g Tafel slopes, and h stability with the controls in HER. The electrolyte is 1.0 M KOH, the scan rate is 5 mV s−1, post-iR compensation is applied. The performance of overall water splitting using FeP–CoP/NC as the catalysts: i the j–t curve at 1.68 V; j the V–t curve at various current densities and k the j–t curve at ±1.68 V with the potential polarity swapped every 3.3 h in a single compartment cell; l the j–t curve at ±1.68 V with the potential polarity swapped every 3.3 h in a H-cell. No iR compensation was applied.
