摘要
Electrocatalytic full water splitting is still a challenge. Porous single-crystalline (PSC) has a long-range ordered crystal structure and large specific surface area, which has great potential to be applied in the fields of catalysis and energy storage. Nitride single-crystalline possesses unsaturated coordination of metal-nitrogen active sites on the crystal surface, which has shown excellent performance in the electrocatalytic field. PSC tungsten nitride mesoporous nanosheets are grown from single-crystalline (SC) WO3 nanosheets and are applied as bifunctional electrocatalysts in Hydrogen Evolution Reaction (HER) and Oxygen Evolution Reaction (OER). The overpotential of mesoporous W2N and WN single-crystalline nanosheets in HER is as low as 67.44 mV and 84.26 mV at a current density of 10 mA cm−2, respectively. A low overpotential has been found in PSC W2N and WN as the OER electrocatalyst. The PSC tungsten nitride mesoporous nanosheets provide a simple and effective solution for efficient water splitting electrocatalysts.
