SUBRAMANIA, A.; PRIYA, A.R.S.  and  MURALIDHARAN, V.S.. Electrocatalytic Behaviour of Nickel-Cerium Alloy Deposits. Port. Electrochim. Acta [online]. 2007, vol.25, n.4, pp.481-488. ISSN 0872-1904.

Electrodeposition of Ni-Ce alloy on steel was studied and  an electroplating bath was optimized for maximum cathodic current efficiency. Cerium sulphate content in the bath decreased the cathodic current efficiency. Hydrogen evolution reaction from NaOH solution was catalysed by cerium in the alloy and also the increase of cerium content increased the catalytic activity. Among the various Ni-Ce alloys, Ni₇₇Ce₂₃ alloy offered the maximum catalytic activity.

Keywords : electrodeposition; Ni-Ce alloy; electrocatalysis; NaOH; hydrogen evolution reaction.
