Heterostructured NiFe Oxide/Phosphide Nanoflakes for Efficient Water Oxidation


To realise the gradual replacement of noble metal-based materials for electrocatalytic energy conversion, numerous endeavors may need to be invested on the compounds based on cheap 3d transition metals (Fe, Co, etc.). For the achievements in energetic electrocatalysis, elaborately designed nanostructures are in urgently desired. Here, we reported a facile approach for the preparation of NiFe oxide/phosphide (Ni2/3Fe1/3O/Ni4/3Fe2/3P) heterostructure with a 2-dimensional (2D) nanoflakes morphology. Benefited from the combined advantages of composition and structure, the 2D Ni2/3Fe1/3O/Ni4/3Fe2/3P nanoflakes were characterized to exhibit a high activity in electrocatalytic water oxidation, surpassing the individual Ni2/3Fe1/3O or Ni4/3Fe2/3P nanoplates. This result may offer a great possibility of delicatedly designing nanostructures for highly efficient electrochemical energy conversion.
