title: Coating a stainless steel plate with silver nanoparticles by the sonochemical method.
abstract: Ultrasound irradiation is used for the deposition of silver nanoparticles with an average size of 40 nm on the surface of a stainless steel plate. The sonochemical reduction of an AgNO(3) solution (water, ethylene glycol and aqueous ammonia) was carried out at 30°C. Irradiation was done with a high intensity ultrasonic horn (Ti horn from Sonics and Materials VCX600, 20 kHz, 600 W at 70% efficiency) under an argon flow. The influence of the distance of the stainless steel plate from the sonicator tip varied, and a homogeneous coating without agglomeration was achieved at a distance of 1 cm. By controlling the reaction conditions and the distance from the tip we could achieve a homogeneous monolayer coating of silver nanoparticles on the stainless steel surface. The silver-deposited stainless steel plates were analysed by UV-visible, XRD, SEM and FIB analyses.
