Synthesis of Manganese Carbonate Templates with Different Morphologies and Their Application in Preparing Hollow MoS2 Micro/Nanostructures for Photocatalysis
Spherical manganese carbonate (MnCO3) templates were successfully prepared by a facile chemical precipitation method. The size of the as-prepared samples was changed by adjusting the ratio of MnSO4·H2O and NaHCO3 (1:1, 1:5, 1:10 and 1:15). More interestingly, when adding Na2SO4 to the reaction solution, the morphology of MnCO3 further evolved from an irregular spheroid to a cube. Next, spherical and cubic MnCO3 particles with the most uniform size were selected as precursor templates to synthesize intermediate compounds (MnCO3/MnS/MoS2). Eventually, MoS2 microspheres and microcubes with a hollow structure were obtained by removing the MnCO3 and MnS with acid pickling. The structure, morphology and elemental composition of the products were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and energy dispersive spectrometry (EDS). The results of the photocatalytic experiments show that hollow MoS2 prepared with an MnCO3 template exhibited excellent photocatalytic performance. Therefore, the application of a template method to prepare hollow structure materials is worthy of further study in the photocatalysis field.
