Abstract
Cadmium sulfi de (CdS) quantum dots (QDs) were synthesized by a standard hydrothermal method with simultaneous desulfurization of kerosene oil. Sulfur containing kerosene oil was treated with cadmium chloride (CdCl2) in the presence of sodium hydroxide (NaOH) at 120 °C for 1.5 to 5 h. CdS was formed and sulfur content of oil gradually decreased. Thus, desulfurization of the oil occurred with the formation of the CdS QDs. The concentration of sulfur decreased to a minimum of 0.055% after 5 h of the reaction. In addition, the particle size of QDs increased from 5.4 nm to 8.1 nm as the reaction time was increased from 1.5 to 5 h. Transmission electron microscopy (TEM) study revealed the formation of CdS QDs of particle size 5.4–8.1 nm.Keywords
