Abstract
- Molybdenum disulfide (MoS2) was synthesized via hydrothermal process under the assistance of citric acid, which exhibited high photocatalytic property in the application of methylene blue (MB) degradation. The flower ball microstructure of MoS2 changed with different amounts of citric acid. X-ray diffraction (XRD), Scanning electron microscope (SEM), UV-Vis diffuse reflectance spectra have been employed to characterize the samples. It improved the photocatalytic efficiency nearly 19.77% compared to MoS2 without citric acid. When H2O2 was added, the synergistic effect of MoS2 and hydrogen peroxide (H2O2) was observed in photocatalytic reaction system, which degraded MB completely within 40 min under visible light irradiation.
