Single and few layer molybdenum disulfide (MoS2) was exfoliated from the bulk form through a liquid phase exfoliation procedure. Highly concentrated suspensions were prepared that were stabilized against reaggregation through adsorption of nonionic polymers to the sheet surface. These exfoliated particles showed strong photoluminescence at an energy of 1.97 eV which is in the visible-light region. These exfoliated MoS2 sheets were then used to catalyze the degradation of a model dye upon exposure to visible light.
单层和少层二硫化钼（MoS2）通过液相剥离程序从块状形式剥离。通过非离子聚合物吸附到片层表面来稳定高度浓缩的悬浮液，防止其重新聚集。这些剥离的颗粒在 1.97eV 的能量下显示出强烈的光致发光，处于可见光区域。然后，将这些剥离的 MoS2 薄片用于在暴露于可见光时催化模型染料的降解。
