Hydrothermal synthesis of gold nanoplates with different size ranges

Gold nanoplates (NPs) were fabricated through a facile hydrothermal method with cetyltrimethylammonium chlorine (CTAC) as a surfactant agent. The morphology and size of the gold NPs could be manipulated by changing the molar ratio of ([CTAC]/[HAuCl4] during the preparation. Triangular, truncated triangular and hexagonal gold nanoplates can be obtained and the sizes of these gold NPs can be varied from a few tens of nanometers, to several hundreds of nanometers, and even a few microns in width.
