Problems solved by technology

If the sewage is directly discharged into the natural environment, it will cause serious water pollution, causing immeasurable impact and loss on society and human health. In addition, the use of drugs and personal skin care products such as antibiotics will lead to water pollution. Pollutants such as antibiotics, which accumulate in the environment and in the human body, can cause acute or chronic disease and enhance bacterial resistance

Abstract

The invention discloses a preparation method of a sponge with a photocatalytic function, wherein the preparation method comprises the steps: assembling a layer of graphene oxide on the sponge by using an electrostatic assembly method, and then loading a layer of nano titanium dioxide on the surface of the graphene oxide in the sponge to obtain the sponge with the photocatalytic function. The prepared sponge with the photocatalysis function is porous, has the capacity of decomposing pollutants under visible light and can be used as a filter screen for air and water, and the purpose of purifying the air and the water is achieved.

Description

Technical field [0001] The present invention belongs to the technical field of photocatalytic material, particularly relates to a method of preparing a sponge having a photocatalytic function. Background technique [0002] With the rapid development of modern industry, air and water pollution has become one of the serious problems facing humanity, such as in the metallurgical processing, mining industry, chemical materials and products industry, leather products and footwear, metal and electronic products industry , paper and textiles and other important industrial production of a large amount of organic waste water. If the sewage is discharged directly into the natural environment, can cause serious water pollution, social, human health have had an impact and incalculable damage, in addition, pharmaceuticals and personal care products such as the use of antibiotics will result in a body of water antibiotics and other pollutants, antibiotics accumulate in the environment and the ...
