Rapid Formation of Silver Shells on Gold Nanorods in a Micellar Solution of Hexadecyltrimethylammonium Chloride

Rapid chemical reduction of silver ions forming silver shells on gold nanorods was realized in a micellar solution of hexadecyltrimethylammonium chloride. It was shown that the stable bilayers of hexadecyltrimethylammonium bromide on gold surfaces contributed to retard the chemical reduction of silver ions on the gold surfaces.
