1. A method of preparing alloy nanoparticles comprising:
- contacting at least one first metal-containing component with a reducing agent to form a first reaction mixture;
heating the first reaction mixture to a first temperature;
incorporating at least one second metal-containing component different from the first metal-containing component and at least one capping agent into the first reaction mixture at the first temperature to form a second reaction mixture;
heating the second reaction mixture to a second temperature;
cooling the second reaction mixture; and
precipitating alloy nanoparticles from the cooled second reaction mixture.
