abstract = {Developing high performance anode catalysts for oxygen evolution reaction (OER) and hydrazine oxidation reaction (HzOR) at large current density is an efficient pathway to produce hydrogen. Herein, we synthesize a FeWO4-WO3 heterostructure catalyst growing on nickel foam (FeWO4-WO3/NF) by a combination of hydrothermal and calcination method. It shows good catalytic activity with ultralow potentials for OER (η10 = 1.43 V, η1, 000 = 1.56 V) and HzOR (η10 = −0.034 V, η1, 000 = 0.164 V). Moreover, there is little performance degradation after being tested for 100 h at 1, 000 (OER) and 100 (HzOR) mA·cm−2, indicating good stability. The superior performance could be attributed to the wolframite structure and heterostructure: The former provides a high electrical conductivity to ensure the electronic transfer capability, and the later induces interfacial electron redistribution to enhance the intrinsic activity and stability. The work offers a brand-new way to prepare good performance catalysts for OER and HzOR, especially at large current density.}
