Abstract
The invention discloses a preparation method of porous nano stannous oxide and belongs to the technical field of preparation of nanomaterials. The preparation method comprises the following steps: a pre-modified porous material and a stannous oxide solution are mixed in a mass ratio being 1:5-1:6, filtering and drying are performed after stirring and mixing, a modified porous material is obtainedand mixed with water in a mass ratio being 1:10-1:15, protease accounting for 0.2-0.3 times the mass of the modified porous material is added, filtering is performed after stirring and mixing, then aproduct is washed until a washing liquid contains no chloride ion under detection of silver nitrate, vacuum drying is performed, and a pretreated modified porous material is obtained; the pretreated modified porous material is heated in an argon atmosphere, cooling and discharging are performed, a porous nano stannous oxide blank is obtained and mixed with an ammonium chloride solution in a mass ratio being 1:5-1:8, filtering and drying are performed after stirring and mixing, and porous nano stannous oxide is obtained. Porous nano stannous oxide prepared with the technical scheme has the characteristics of excellent particle size uniformity and porosity.
