A kind of high activity self-supporting OER electrocatalyst material and its preparation method and application |
| abstract |
The invention provides a high-activity self-supporting OER electrocatalyst material and a preparation method and application thereof. The electrocatalyst material includes a nickel foam substrate and a NiFe 2 O 4 /Ni 3 S 4 /Ni(OH) 2 material with a heterostructure grown on the foam nickel substrate in situ. The present invention also provides a method for preparing the above electrocatalyst material, comprising the steps of: placing the pretreated nickel foam in an iron source aqueous solution to perform a hydrothermal reaction; after the reaction is completed, washing and drying to obtain NiFe 2 O 4 /Ni (OH) 2 /NF composite material; the obtained NiFe 2 O 4 /Ni(OH) 2 /NF material is placed in a sulfur source aqueous solution to carry out a vulcanization reaction; after the reaction is completed, it is obtained by washing and drying. The present invention is a heterostructure of in-situ growth of NiFe 2 O 4 /Ni 3 S 4 /Ni(OH) 2 on the NF three-dimensional framework, and has excellent electrocatalytic performance. |
