Gold deposition from 1-butyl-1-methyl-pyrrolidinium dicyanamide ionic liquid at...

Sá, A. I. Correia de; Eugénio, S.; Quaresma, S.; Rangel, C. M.; Vilar, R.

In this work, the deposition of gold on copper substrates from solutions of HAuCl4.3H2O in 1-butyl-1-methylpyrrolidinium dicyanamide was studied. Deposition was carried out in open-circuit and under potentiostatic control at temperatures from 293 to 353 K, in normal atmosphere, with deposition conditions allowing water from atmospheric absorption up to 0.8 wt.%. Films of gold were obtained by both methods. Dep...

Sá, A. I. Correia de; Eugénio, S.; Quaresma, S.; Rangel, C. M.; Vilar, Rui

Recent research has suggested a number of applications for gold in fuel cells and related hydrogen fuel processing, which include coatings for light weight corrosion resistance bipolar plates and the incorporation of gold as catalyst to provide improvements in electrode conductivity, among others. This paper reports on the electroless deposition of gold on copper substrates from a HAuCl4.3H2O solution in 1-buty...
