Abstract

The invention provides a preparation method for a photo-catalysis material with an aerogel substrate and relates to the preparation method for the photo-catalysis material. The preparation method is mainly used for solving the technical problem of low photo-catalysis effect caused by the difficulty in utilizing the functionality of the embedded nanometer material of the present nanometer material loading substrate. The preparation method comprises the following steps: 1) weighting nanometer materials with photo-catalysis activity, ionic liquid and celluloses in proportion; 2) uniformly dispersing the nanometer materials in the ionic liquid, and then adding the celluloses, thereby obtaining blended liquid; 3) pouring the blended liquid obtained in the step 2) into a mould, cooling, and then pouring into a regenerating solution, and depositing and regenerating, thereby obtaining a compound gel; and 4) drying the compound gel prepared in the step 3), thereby obtaining the photo-catalysis material with the aerogel substrate. The photo-catalysis material provided by the invention can be used for catalytically degrading the organic pollutants or harmful strains, such as escherichia coli, and the like.

Description

technical field

[0001] The invention relates to a preparation method of a photocatalytic material. Background technique

[0002] Research on inorganic nanoparticle / polymer composites is now an active field. Organic-inorganic composites combine the properties of organic and inorganic materials for superior performance. Nanoscale metal and metal oxide (semiconductor) particles, such as gold, titanium dioxide, zinc oxide, and iron oxide, are advanced functional materials because of their unique size physicochemical effects and photoelectric effects. Metal oxide nanoparticles have many applications in photoelectrocatalysis, photocatalysis and biomedicine. In particular, titanium dioxide nanomaterials have attracted more attention due to their potential photoelectric activity, solar energy conversion performance, self-cleaning surface and photocatalytic activity in air purification and water purification. Some organic pollutants, such as ethanol, phenol, organic dyes, and carb...
