Preparation of [C_(60)]Fullerene-CoS2 Nanocomposites and Kinetics Study for Photocatalytic Degradation of Organic Dyes

摘要

Nanosized cobalt disulfide (CoS2) particles were synthesized with 0.08 M cobalt chloride hexahydrate (CoCl2·6H2O) and 0.2 M sodium thiosulfate pentahydrate (Na2S2O3·5H2O) dissolved in distilled water under microwave irradiation. [C_(60)]Fullerene-CoS2 nanocomposites were prepared with nanosized CoS2 particles and [C_(60)]fullerene as heated by 700 °C for 2 h in an electric furnace. X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) identified the heated [C_(60)]fullerene-CoS2 nanocomposites. Heated [C_(60)]fullerene-CoS2 nanocomposites were investigated the activity of photocatalytic degradation as a catalyst in various organic dyes like acid yellow 23, methylene blue, methyl orange, and rhodamine B with ultraviolet light at 254 nm by UV-vis spectrophotometer.
