Preparation method of nano molybdenum disulfide composite natural polysaccharide microspheres based on confinement space

The invention discloses a preparation method for synthesizing nano molybdenum disulfide loaded natural polysaccharide microspheres through confinement space design. Comprising the following steps: step 1, preparing natural polysaccharide microspheres, dissolving natural polysaccharide by using an alkali urea solvent system, performing emulsification regeneration, filtering and washing to obtain microspheres; step 2, preparation of a precursor: dissolving thiourea and ammonium molybdate heptahydrate in water, then adding a certain amount of microspheres obtained in the step 1, and soaking for a period of time; step 3, hydro-thermal synthesis: pouring the solid-liquid mixture obtained in the step 2 into a hydro-thermal reaction kettle, and reacting for a certain time at the temperature of 200 DEG C or below; and 4, filtering and washing the mixture obtained in the step 3 to obtain the natural polysaccharide-nano molybdenum disulfide composite microspheres. The method is low in raw material cost and simple in pr
