Dr. Katja Skorb (Max Planck Institut of Colloids and Interfaces) and Dr. Daria Andreeva (University of Bayreuth) developed a one-step method to produce metal nanocomposites from metal alloys under ultrasound irradiation. Systematic investigation of ultrasound effects on various metal particles reveals cavitation-induced recrystallization and oxidation of metals as main factors in the process. The fact that different metals react in dramatically different fashion towards ultrasound irradiation was exploited for the formation of nanoscale composites. The application of the novel mesoporous nanocomposites as effective nanocatalysts is published in ChemComm:
