文摘
- •
Glycine can inhibit the reduction of Ni2+ ions but promote the reduction of Mn2+ ions.
- •
Glycine changes the mode of Ni–Mn film growth from Volmer–Weber mode into Stranski–Krastanov mode.
- •
Glycine promotes the dissolution of both Ni and Mn deposits in the ChCl–urea ionic liquids.
- •
The Mn content in the Ni–Mn film depends on the concentration of glycine and current density.
- •
The Ni–Mn film with 3.1 at.% Mn content exhibits better corrosion resistance than pure Ni film.
