Synthesis and optimisation of nickel : iron for electrocatalytic evolution
Owing to the abundance of Iron (Fe) and Nickel (Ni) in the Earth's crust and the relative good Oxygen Evolution Reaction (OER) electrocatalytic activity of NiO_x and FeO_x, the search for an optimal Ni : Fe-based catalyst as OER electrocat- alyst has become the motivation of this project....

| description | Owing to the abundance of Iron (Fe) and Nickel (Ni) in the Earth's crust and the
relative good Oxygen Evolution Reaction (OER) electrocatalytic activity of NiO_x
and FeO_x, the search for an optimal Ni : Fe-based catalyst as OER electrocat-
alyst has become the motivation of this project. By varying the molar ratios of
metal and viscosity of the Ni : Fe precursors, the dip-coated Ni : Fe carbon cloth
was annealed at di erent temperatures. This study achieved an optimised Ni : Fe
electrocatalyst with superior OE electrocatalytic activities as a non noble metal
catalyst. The fabricated Ni80% : Fe20% electrocatalyst annealed at 400 C,
requires a low overpotential of 278:4 mV to achieve current density of 10 mA/cm^2 with a Tafel slope of 53.7 mV dec^-1. Moreover, the Ni80 % : Fe20% electrocatalyst exhibits stable chronopotentiometric behaviours over a duration of 20 hours under constant current density of 10 mA/cm^2 and 30 mA/cm^2. |
