Abstract

Gas-liquid interface discharge at atmospheric pressure above HAuCl4 solutions containing no protective agents generates triangular and hexagonal nanoplates and nanorods of gold. Experimental results under several different conditions indicate that the plates and rods rapidly grow on the surface of the solution. In contrast, the spherical nanoparticles slowly grow in the solution.
