Data from research on electrocatalysts' activity towards water-splitting

The data set contains the results of studies on the electrocatalytic activity of the transition metal-based compounds towards water-splitting (OER and HER).Here, a single atom ruthenium dispersed in nickel-cobalt layered hydroxide (Ru-NiCo LDH) is reported. Through the precise controlling of the atomic dispersion and local coordination environment, Ru-NiCo LDH//Ru-NiCo LDH provides an ultra-low overpotential of 1.45 mV at 10 mA cm−2 for the overall water splitting, which surpasses that of the state-of-the-art Pt/C/RuO2 redox couple. Thus, Ru-NiCo LDH shows enhanced water splitting performance with potential for the development of promising water-alkaline catalysts.
