A nano-hybrid catalyst, comprising:
- a two-dimensional platinum (Pt) nanodendrite sheet with a controlled crystal plane;
- and
- a NiFe layered double hydroxide nanosheet layer,
- wherein the two-dimensional platinum (Pt) nanodendrite sheet with the controlled crystal plane and the NiFe layered double hydroxide nanosheet layer are alternately stacked, and
- wherein in the two-dimensional platinum (Pt) nanodendrite sheet with the controlled crystal plane, each of Pt nanocrystals has a shape of a hexagonal disk surrounded by a (110) crystal surface as a basal plane, a (111) plane and a (100) plane, and the Pt nanocrystals are interconnected via the (111) plane, and the (110) crystal surface is exposed.
