摘要：In this work, a series of nanostructured molybdenum disulfide (MoS2) with various morphologies, such as spherical, flower-like, coil and hollow were synthesized via a one-step hydrothermal method. The photocatalytic properties of as obtained MoS2were evaluated by degrading methylene blue (MB) under visible light. Interestingly, the flower-like MoS2 exhibited the best photocatalytic activities. It is ascribed that the suitable porous structures of flower-like MoS2 can increase the number of exposed active sites, which facilitate the efficient adsorption and transfer of MB to the active sites. Meanwhile, the special structure of flower-like MoS2 can improve light absorption efficiency owing to the increasing of light paths. Furthermore, its 2D stacked petals possess abundant active sites, which will effectively affect the photocatalytic efficiency. This study indicates that the surface area of nanomaterials is not a dominated factor in photocatalytic performance. The surface morphology has a great influence on the photocatalytic performance, which provides a feasible guide for synthesizing efficient photocatalytic nanomaterials.
