Objective To explore four methods for synthesizing molybdenum disulfide nanoflowers,and develop a potential photothermal material. Methods Four kinds of methods for synthesizing a series of molybdenum disulfide nanoflowers by conventional solvothermal synthesis,citric acid solvothermal synthesis,citrate solvothermal synthesis,and solvothermal synthesis by mesoporous silica spheres were developed.Transmission electron microscope (TEM) was performed to screen appropriate method to synthesize molybdenum disulfide nanoflowers.The structure and properties were characterized by UV,IR and photothermal curves. Results The nano-structures of molybdenum disulfide were obtained by four kinds of synthetic methods.The results showed that molybdenum disulfide nanoflowers synthesized using mesoporous silica spheres solvation method possessed uniform morphology,uniform size distribution and good water dispersibility. Conclusion Mesoporous silica sphere solvation method can obtain molybdenum disulfide nanoflowers with excellent properties.It was a new method for synthesizing molybdenum disulfide nanoflowers which were potential for further applications.
