Synthesis of CdS nanocrystals and Au/CdS nanocomposites through ultrasound activation liquid–liquid two-phase approach at room temperature

CdS nanocrystals were prepared and further 50 times scale-up syntheses were carried out through a novel ultrasound activation liquid–liquid (water and cyclohexane) two-phase approach at room temperature for the first time. Further preparation of Au/CdS nanocomposites were also realized by the same method. This fast, energy saving, environmentally benign, high-yield approach will benefit greatly to both fundamental mechanism research and industrial utilization development.
