Mechanism of Formation of Metal Sulfide Ultrafine Particles in Reverse Micelles Using a Gas Injection Method

摘要

The mechanism of formation of ultrafine CdS, ZnS, and their composite particles by the injection of H_2S into reverse micelles was studied. The particle formation process was followed by the change in UV-visible absorption spectra. The kinetics of the whole process including dissolution of H_2S, nucleation, particle growth, and coagulation was analyzed from time-course changes of the size and number of formed particles.
