Embodiment 1
[0021] An indoor air deodorant, which is composed of the following materials in parts by weight: 1 part of amino acid functionalized graphene oxide, 2 parts of sodium percarbonate, 0.03 part of citric acid, and 5 parts of nano titanium dioxide.
[0022] A preparation method of indoor air deodorant, comprising the following steps:
[0023] 1) Take sodium percarbonate and nano-titanium dioxide, mix uniformly, and make powder;
[0024] 2) dissolving citric acid to make 5wt% citric acid aqueous solution;
[0025] 3) ultrasonically dispersing the amino acid-functionalized graphene oxide in pure water, adding a citric acid aqueous solution dropwise thereto, and standing for 2 hours to form a mixed solution;
[0026] 4) Add the powder into the mixed solution, stir evenly, and let it stand for 3 hours to obtain.
Embodiment 2
[0028] An indoor air deodorant, which is composed of the following materials in parts by weight: 5 parts of amino acid functionalized graphene oxide, 6 parts of sodium percarbonate, 0.05 parts of citric acid, and 10 parts of nano-titanium dioxide.
[0029] A preparation method of indoor air deodorant, comprising the following steps:
[0030] 1) Weigh sodium percarbonate and nano-titanium dioxide, mix uniformly, and make powder;
[0031] 2) citric acid is dissolved to make 15wt% citric acid aqueous solution;
[0032] 3) ultrasonically disperse the amino acid functionalized graphene oxide in pure water, add dropwise citric acid aqueous solution to it, and let it stand for 4 hours to form a mixed solution;
[0033] 4) Add the powder into the mixed solution, stir evenly, and let it stand for 5 hours to obtain.
Embodiment 3
[0035] An indoor air deodorant, which is composed of the following materials in parts by weight: 1 part of amino acid functionalized graphene oxide, 2 parts of sodium percarbonate, 0.03 part of citric acid, and 6 parts of nano-titanium dioxide.
[0036] A preparation method of indoor air deodorant, comprising the following steps:
[0037] 1) Take sodium percarbonate and nano-titanium dioxide, mix uniformly, and make powder;
[0038] 2) dissolving citric acid to make 8wt% citric acid aqueous solution;
[0039] 3) ultrasonically dispersing the amino acid-functionalized graphene oxide in pure water, adding a citric acid aqueous solution dropwise thereto, and standing for 2 hours to form a mixed solution;
[0040] 4) Add the powder into the mixed solution, stir evenly, and let it stand for 3 hours to obtain.
