example 1

[0025]Mix soybean protein isolate and sodium hydroxide solution with a mass fraction of 5% in a beaker at a mass ratio of 1:3, and add distilled water 10 times the amount of soybean protein isolate to the beaker, at a temperature of 88°C and a rotation speed of 400r / Under the condition of stirring and mixing for 50 minutes, the soybean protein gel was obtained. The soybean protein gel was mixed with the organic aldehyde solution at a mass ratio of 9:1. After standing and aging at room temperature for 26 hours, the soybean protein gel was obtained. The soybean protein gel was pulverized, frozen in liquid nitrogen for 6 minutes, and then vacuum-dried to obtain a protein porous material; the protein porous material and trioctylamine were mixed in a flask at a mass ratio of 1:8, and the protein porous material was added to the flask Oxalic acid with 3 times the mass was stirred and mixed for 40 minutes at a temperature of 55°C and a rotational speed of 400r / min, and then filtered ...

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.

Description

technical field [0001] The invention discloses a method for preparing porous nanometer stannous oxide, which belongs to the technical field of nanometer material preparation. Background technique [0002] Porous nano-stannous oxide is a kind of dark gray or brown-black powder, insoluble in water and alcohol, and is odorless or slightly hydrochloric acid odorous metal oxide. It is relatively stable in the air and is easily converted into tin oxide (SnO 2 ), dissolved in hydrochloric acid or dilute sulfuric acid to generate stannous salt, dissolved in concentrated strong alkali solution to generate stannous salt. Porous nano stannous oxide has reducibility and can be used as a reducing agent to prepare stannous salt. The stannous salt solution reacts with sodium hydroxide solution to generate stannous hydroxide, which is then heated and decomposed to generate stannous oxide. Therefore it is widely used in fields such as catalyst, electroplating and glass industry. [0003] ...
