Molybdenum sulfide layered double-metal hydroxide complex as well as preparation method and application thereof

The invention provides a molybdenum sulfide layered double-metal hydroxide complex and a preparation method and application thereof. In the molybdenum sulfide layered double-metal hydroxide complex, a molybdenum sulfide anion cluster Mo3S132-is inserted between layers of magnesium-aluminum layered double-metal hydroxide, the magnesium-aluminum layered double-metal hydroxide laminate has good dispersion capacity on an anion cluster Mo3S132-, so that Mo and S adsorption sites of Mo3S132-located between layers are fully exposed, the capturing capacity on Ag is improved, and the adsorption capacity can reach 1073 mg/g. More importantly, the MgAl-Mo3S13-LDH can be used for reducing Ag into metal Ag, so that the elemental silver nano belt is obtained. 本申请提供了一种钼硫化物层状双金属氢氧化物复合体及其制备方法和应用，其中，所述钼硫化物层状双金属氢氧化物复合体中，钼硫化物阴离子簇Mo3S132-插入镁铝层状双金属氢氧化物的层间，镁铝层状双金属氢氧化物层板对阴离子簇Mo3S132-具有良好的分散能力，使位于层间的Mo3S132-的Mo、S吸附位点充分暴露，提高了对Ag+的捕获能力，吸附量可达1073mg/g。更为重要的是，MgAl-Mo3S13-LDH可将Ag+还原为金属Ag，从而获得单质银纳米带。
