The appropriate choice of chemical composition of a metallic precursor, which produces the basic structure units in the growth process of nanocrystals, is a high priority in the synthesis of metal-especially Au-nanoparticles. In the present work, Au seeds (prepared by the reduction of Au3+ solution with NaBH4 in the presence of cetyltrimethylammonium bromide (CTAB)) have been used to initiate the...
The inhibitive action of the four surfactants, cetyltrimethylammonium bromide (CTAB), sodium dodecyl sulfate, sodium oleate and polyoxyethylene sorbitan monooleate (TWEEN-80), on the corrosion behavior of copper was investigated in aerated 0.5 moldm -3 H 2 SO 4 solutions, by means of electrochemical impedance spectroscopy. These surfactants acted as the mixed-type inhibitors...
