Abstract
MoS2 nanostructures were prepared using the hydrothermal method by reacting ammonium heptamolybdate tetrahydrate ((NH4)6Mo7O244H2O) with citric acid monohydrate (C6H8O7H2O) in distilled water with the presence of sodium sulfide (Na2S). The surface structure studies of MoS2 showed that the size of the surface clusters of the studied tablet is of the order of 50 – 100 nm. Using measurements (Zetasizer Nano Series), we found that the particle sizes ranged from 150 – 350 nm. Alternating current (LCR) measurements were made for (tablet-MoS2) under a constant temperature T = 10 0C. Measurements of the parallel electrical capacitance (Cp) in terms of frequency (F) of tablet-Mo2S showed a sharp drop in the value of the electrical capacitance (Cp) with an increase in frequency within the range 20 Hz – 16 kHz. It is shown that the series capacitance increased with the increase of the applied potential.
