Nanoparticle PreparationPhysical Methods• Physical and Physicochemicalh techniques generally involvemore expensive technology butpromise more control overnanoparticle creation.• The main physical methods forcreating nanoparticle catalystsare:- Sonochemistry- Microwave Irradiationi- Pulsed Laser Ablation- Supercritical Fluids- Plasma- Etc.http://ag.arizona.edu/swes/rasmussen/pics/XRD_pics/DSC02074.JPG
Nanoparticle PreparationPhysical Methods• Sonochemistry uses sonic waves toalter molecule properties. affect thesurface structure of the metalsusually enhancing the surfacecontact area.• Microwave Irradiation involvesexposing metal salt solutions tomicrowave irridiation in order toprepare a wide range ofnanocatalysts.• Supercritical fluids can be employedto create supported nanoparticlecatalysts by providing a solutionwith a lower viscosity it and lesssurface tension.http://www.bloodhoundssc.com/_db/_images/sonic_boom.jpg
