A novel Pt anchoring WO3 nanoarray catalyst is reported, which exhibits superior bifunctional performance for HzOR/HER under alkaline conditions. Pt/WO3/NF requires an ultrasmall overpotential of 34.6 and 226.38 mV to achieve 10 and 100 mA cm(-2) for HzOR, respectively. When used for HER-HzOR electrolysis, Pt/WO3/NF requires low voltages of 0.717 V and 1.049 V at 100 and 200 mA cm(-2), respectively.
Herein, a novel Pt anchoring WO3 nanoarray catalyst is reported and its application as HzOR and HER bifunctional electrocatalysts which shown to have superior bifunctional performance for HzOR/HER under alkaline conditions. The Pt/WO3/NF requires an ultrasmall overpotential of 34.6 and 226.38 mV to achieve 10 and 100 mA cm(-2) for the hydrazine oxidation reaction (HzOR), respectively. When used for HER-HzOR electrolysis, Pt/WO3/NF requires low voltages of 0.717 V and 1.049 V at 100 and 200 mA cm(-2), respectively. [GRAPHICS]
