Ultrasound driven formation of metal-supported nanocatalysts

Bimetal nanocatalysts with a narrow pore size distribution and high surface area were prepared using a fast, easy and green method of ultrasound irradiation in water. The concept is demonstrated for the case of aluminum-gold, silver or platinum, but applicable to a large range of nanoparticles. The application as effective nanocatalysts is shown.
