Patent ID: 11110448

Abstract:
Provided is a method for preparing gold nanorods having a high catalytic activity by using a femtosecond laser. The method includes: (1) preparing a gold seed solution; (2) preparing a gold nanorod solution by a seed solution growth process; (3) subjecting the gold nanorod solution to a centrifugal separation to obtain the gold nanorods, and dropping the gold nanorods on a silicon substrate; (4) building a system for preparing the gold nanorods having the high catalytic activity by using the femtosecond laser; and (5) emitting a pulse of the femtosecond laser on the silicon substrate, to allow an electric field distribution of a surface of the gold nanorod on the silicon substrate to change, to partially exfoliate atoms on the surface of the gold nanorod, thereby obtaining the gold nanorod with the high catalytic activity.
