Noble metal (gold; Au, silver; Ag, copper; Cu, palladium; Pd and platinum; Pt) nanoparticles were deposited on activated carbon in aqueous media by irradiation of high-frequency ultrasound in the absence of any additional reductants (e.g., sodium borohydride). The diameter of nanoparticles deposited on the activated carbon was controlled by the concentration of metal salt in the aqueous metal salt solution. Furthermore, we revealed that the ethylene gas in air was removed by Ag, Pd and Pt nanoparticles-deposited activated carbon while the ethylene gas in air was not removed by Au, and Cu nanoparticles-deposited activated carbon and non-deposited activated carbon.
