Background Art

[0002] Most public activities are indoors. As people spend more than 90% of their time indoors, the quality of indoor air (IAQ) will directly affect human health.

[0003] Indoor air quality factors include harmful substances such as volatile organic compounds and formaldehyde, which are mainly released from indoor decoration materials, such as paints or adhesives; or carbon dioxide and ozone emitted by the operation of copiers, harmful gases released by air-conditioning systems or other related pollution sources, etc., which widely and quickly spread bioaerosols; in addition, respirable particulates and various chemical substances caused by human activities such as smoking, in addition to seriously affecting indoor air quality; even worse, it can cause cancer and other acute or chronic diseases.

After stirring for 0.3-3 hours, the stirring is stopped and the solution is allowed to stand. In this process, an exhaust system needs to be used to evacuate air to remove the ammonia water, and finally, a graphene oxide-supported porous silica aerogel crystalline solution can be obtained.

In step S1, the preparation method of the porous silica aerogel crystalline solution is as follows: firstly prepare a first solution and a second solution, wherein the first solution is 1-15 g of silica and 15-30 g / 10-30% tetraethylammonium hydroxide, added to a liquid and stirred to form a uniform white turbid colloidal solution; and the second solution is 0.1-0.8 g of ammonium hydroxide deionized water and 0.1-0.5 g of sodium aluminate is added and stirred to form a sodium aluminate aqueous solution; the first solution and the second solution are mixed and placed in a vacuum oven for reaction for 12-48 hours, and after the reaction is completed, a transparent and clear porous silica aerogel seed solution can be obtained, and the porous silica aerogel seed has a structure (such as Figure 1 As shown), the porous aerogel 1 formed has a plurality of holes. In the step S2, the porous silica aerogel crystalline solution and the graphite oxide are combined in a process, and the preparation method is as follows: 0.05-0.25 grams of hexadecyltrimethylammonium bromide (CTAB) is dissolved in 20-122 grams of deionized water, and 0.1-0.5 grams of 0.1-0.25M sodium dodecyl sulfate (SDS) is added, and then n-decane ethanol solution (such as 200-800 μL decane mixed with 5-25 grams of ethanol) is added.

[0043] In summary, the technical feature of the present invention is that: graphene oxide combined with porous silica aerogel nanoparticles is used as a substrate, and silver nanoparticles-carrying graphene oxide are reduced on the graphene oxide-carrying porous silica aerogel nanoparticles by chemical reduction, wherein the chemical reduction method uses an argon plasma formed by a plasma method to break bonds of water molecules to generate highly active hydroxyl free radicals, so that a high density of silver nanoparticles can be loaded on the graphene oxide-carrying porous silica aerogel nanoparticles that also have free radicals, thereby achieving better adsorption of harmful substances, adsorption of odors, sterilization, antiviral and other effects.

[0044] Furthermore, the silver nanoparticles disclosed in the present invention are loaded on the graphene oxide loaded porous silica aerogel particles, wherein the acid groups between the graphene oxide layers can be used as stabilizing partners to maintain the chemical stability of the silver nanoparticles, and the acid groups between the graphene oxide layers can generate electrostatic properties, which further helps to adsorb more volatile organic compound (VOCs) particles or molecules. In addition, the oxygen functional groups between the graphene oxide layers can increase the number of active oxygen sites, making it easier to adsorb carbon particles, metal particles and aromatic molecules in the air, so that the graphene oxide can enhance the adsorption effect of the silica aerogel.

[0045] In addition, the silver nanoparticles disclosed in the present invention are loaded on the porous silica aerogel particles loaded with graphene oxide, wherein the porous silica aerogel can absorb and reduce the indoor odor that makes people uncomfortable, thereby producing a catalytic effect through the nano-silver loaded with graphene, which is also mixed in the porous silica aerogel, and the odorous substances adsorbed by the porous silica aerogel are effectively decomposed, and the deodorizing effect is sustained.

[0046] The silver nanoparticles disclosed in the present invention are loaded on the graphene oxide loaded porous silica aerogel particles, which can be made into coatings after grafting, for example, deodorizing coatings, so that the coatings can be perfectly bonded, and the brush resistance and scrubbing effects are increased, instead of the traditional embedding method, which is only a physical bonding. After washing with water, the porous silica aerogel particles are easily physically disappeared.
