Synthesis of thermally stable monodispersed Au@SnO2 core–shell structure nanoparticles by a sonochemical technique for detection and degradation of acetaldehyde

A simple ultrasound assisted chemical precipitation technique for the synthesis of Au@SnO2 core-shell structure nanoparticles is reported. Au nanoparticles were synthesized via chemical reduction of metal salt followed by sonochemical deposition of a tin dioxide shell with controlled shell thickness. The phase and morphology have been inv...More
