Embodiment 1
[0027] A core-shell structure AuRh star-shaped decahedral nanocrystal, and its preparation method is:
[0028] (1) under room temperature condition, dissolving chloroauric acid in 3 milliliters of oleylamine, stirring uniformly with magnetic force, and preparing a chloroauric acid solution with a concentration of 0.01 mol / L;
[0029] (2) 7 ml of oleylamine was added to a 25 ml three-necked flask, the three-necked flask was placed in an oil bath at 180 degrees Celsius, the magnetic stirring was preheated for 10 minutes, and the gold chloride prepared in step (1) was quickly injected with a pipette The acid solution continued to react for 3 hours. After the reaction, the product was centrifuged and washed three times with cyclohexane and ethanol, and the obtained black precipitate was redispersed in 10 milliliters of oleylamine solution to obtain a gold particle seed solution;
[0030] (3) under room temperature condition, hexadecyl trimethyl ammonium chloride is dissolved in 5 ...
