preparation example Construction

[0023] The preparation method of nano air purification catalyst comprises the following steps:

[0024] Step 1: adding modified titanium dioxide with visible light catalytic performance into deionized water, ultrasonically dispersing for 8 to 15 minutes to form a gel, adding platinum particles and stirring magnetically for 12 to 18 minutes to obtain A solution.

[0025] Step 2: Add methylcellulose and sodium dodecylbenzenesulfonate to another portion of deionized water and stir evenly, slowly add graphene powder under magnetic stirring and continue stirring for 25-35 minutes, then add Alkyl sodium sulfate, carboxymethyl cellulose, nano-anion powder and nano-silver are magnetically stirred for 25-35 minutes to obtain B solution. In order to prevent the agglomeration of graphene, the preparation sequence cannot be reversed.

[0026] Step 3: Mix the above-mentioned solution A and solution B and perform magnetic stirring for 25 to 35 minutes to prepare a composite solution of nan...

Embodiment 1

[0028] Step 1: Add 100g of titanium dioxide with a particle size of 5nm into 1L of deionized water, disperse it by ultrasonic wave for 10 minutes to form a gel, add 50g of platinum particles with a particle size of 1nm and stir magnetically for 15 minutes to obtain A solution.

[0029] Step 2: Add 60g of methylcellulose and 18g of sodium dodecylbenzenesulfonate into 1L of deionized water and stir evenly, slowly add 250g of graphene powder with a particle size of 100nm under magnetic stirring and continue stirring for 30 minutes , then add 60g sodium alkyl sulfate, 40g carboxymethyl cellulose, 20g nano-anion powder and 3g particle diameter to be the nano-silver of 20nm and carry out magnetic stirring for 30 minutes, obtain B solution.

[0030] Step 3: Mix the above-mentioned solution A and solution B and perform magnetic stirring for 30 minutes to prepare the nanometer air purification catalyst composite solution S1.

Embodiment 2

[0032] Step 1: Add 50g of titanium dioxide with a particle size of 5nm into 1L of deionized water, disperse it by ultrasonic wave for 10 minutes to form a gel, add 25g of platinum particles with a particle size of 1nm and stir magnetically for 18 minutes to obtain A solution.

[0033] Step 2: Add 30g of methylcellulose and 15g of sodium dodecylbenzenesulfonate into 1L of deionized water and stir evenly, slowly add 100g of graphene powder with a particle size of 100nm under magnetic stirring and continue stirring for 35 minutes , Then add 40g sodium alkyl sulfate, 70g carboxymethyl cellulose, 50g nano-anion powder and 20g particle diameter to be the nano-silver of 20nm and carry out magnetic stirring for 35 minutes, obtain B solution.

[0034] Step 3: Mix the above-mentioned solution A and solution B and perform magnetic stirring for 30 minutes to prepare the nanometer air purification catalyst composite solution S2.

Abstract

The invention discloses a nano air purifying catalytic agent and a preparation method thereof. The nano air purifying catalytic agent comprises the following components in percentage by mass: 1%-10% of titanium dioxide, 0.5%-5% of nano platinum, 1%-3% of methylcellulose, 0.5%-1.5% of sodium dodecyl benzene sulfonate, 1%-20% of graphene, 1%-10% of sodium alkyl sulfate, 1%-5% of carboxymethylcellulose, 0.5%-5% of nano negative-ion powder, 0.05%-2% of nano silver and the balance of deionized water. The nano air purifying catalytic agent can continuously purify indoor air for 24 hours in the whole day under the condition of light or no light.

Description

technical field [0001] The invention relates to a product for purifying pollution from interior decoration, in particular to a nanometer air purification catalyst for removing harmful gases from interior decoration and a preparation method thereof. Background technique [0002] Huang Yaohua, director of the China Children's Health Care Disease Prevention and Control Guidance Center, disclosed at the "First China Indoor Environmental Pollution and Children's Health Symposium" that at present in China, about 2.1 million children die each year from respiratory infections caused by decoration pollution, and 90% of them are children. The homes of children with leukemia have recently been renovated. [0003] The World Health Organization reports that there are four main sources of indoor air pollution, such as building materials such as cement, paint, paint and furniture. Pollutants in indoor air mainly include chemical pollutants such as formaldehyde, benzene, ammonia, and TVOC,...
