Water is highlighted focused because it is the only available source of hydrogen marked as fossil free. Among all the frequently used techniques, electrochemically splitting water possesses the predominant position, while it only accounts for 4% of globally producing hydrogen. However, the high cost and low efficiency of catalysts promoting the oxygen evolution reaction (OER) are main reasons causing the relatively low production rate. Here, we constructed RuO2nanosheets (NRO NSs) by the exfoliation of layered RuO2intercalated with sodium nanoparticles (NRO NPs). To optimize the catalytic properties of noble metals, turning atom arrangement can be a way to reach the aim. NRO NSs exhibit superior electrocatalytic activity toward OER with a low overpotential of 220 and 330 mV to stimulate the current densities of 10 and 100 mA cm−2in acidic electrolyte. After running for 20 h at 1.45 V vs. RHE (reversible hydrogen electrode), NRO NSs catalyst does not show obvious deactivation or decomposition, demonstrating that high stability for NRO NSs can be achieved while retaining high activity for OER. This work offers a new perspective for designing admirable electrocatalysts and the two-dimensionalization of bulk materials.Graphical abstract
