Abstract

The invention discloses a preparation method of attapulgite-loaded nano-sized strontium titanate. The preparation method comprises the following steps: weighing strontium acetate and tetrabutyl titanate according to a molar ratio of 1: 1, then dissolving strontium acetate into distilled water to obtain a solution A, and dissolving tetrabutyl titanate into isopropanol to obtain a solution B; while magnetically stirring, dropwise adding the solution A into the solution B, continuing stirring for 2-4 min, standing and aging, then adding purified attapulgite, stirring for 10-15 min, filtering, placing for 1-2 days, drying till a constant weight, presintering for 1-3 h at 200-250 DEG C, increasing the temperature to 380-420 DEG C, keeping the constant temperature for 2-4 h, then increasing the temperature to 590-630 DEG C, keeping the constant temperature for 1-2 h, then increasing the temperature to 770-810 DEG C, keeping the constant temperature for 0.5-1 h, naturally cooling, and taking out on the next day. Attapulgite-loaded nano-sized strontium titanate can efficiently and rapidly adsorb and decompose formaldehyde, benzene, ammonia, TVOC and other harmful gases so as to achieve purifying, disinfecting, deodorizing and sterilizing purposes.

Description

technical field [0001] The invention relates to a preparation method of attapulgite loaded nano strontium titanate, which belongs to the field of photocatalyst materials. Background technique [0002] Attapulgite is a kind of water-rich magnesium aluminum silicate clay mineral with layer chain structure. Due to the special structure of attapulgite, it has many excellent characteristics, such as good adsorption capacity, unique dispersibility, resistance High temperature, salt-alkali resistance, high plasticity and cohesive force, the mineral itself is light, brittle, strong water absorption, large specific area, small shrinkage after drying, no significant cracks, soaked in water, collapsed, suspension encountered The electrode does not flocculate or precipitate, so attapulgite has a wide range of applications and can be used as an adsorbent, catalyst, gelling agent, filler, suspending agent, thickener, decolorizer, etc. [0003] The photocatalyst material will produce a ph...
