Abstract

The invention provides a graphene composite material for removing formaldehyde and a preparation method of the graphene composite material. The preparation method comprises the steps: firstly, carrying out modification treatment on titanium oxycarbonitride by utilizing gamma-methacryloxypropyltrimethoxysilane to obtain modified titanium oxycarbonitride; then carrying out modification treatment onsilicon and boron co-doped graphene by utilizing 3-aminopropyltriethoxysilane to obtain modified graphene; and finally, carrying out mixing reaction on the modified titanium oxycarbonitride, the modified graphene and the modified silica gel to obtain the graphene composite material. The modified silica gel is obtained by carrying out modification treatment on silica gel by utilizing 3-aminopropyltrihydroxysilane. The graphene composite material can catalytically oxidize formaldehyde into harmless carbon dioxide and water at normal temperature, and formaldehyde can be thoroughly removed in a short time.

Description

technical field [0001] The invention relates to the technical field, in particular to a graphene composite material for removing formaldehyde and a preparation method thereof. Background technique [0002] Formaldehyde is a colorless gas with a strong pungent odor at normal temperature and pressure, and is easily soluble in water, alcohols and ethers. Indoor decoration materials, such as wood-based panels and products, paints and carpets, etc., mostly use formaldehyde in the production process. Due to the above-mentioned characteristics of formaldehyde, these materials will release formaldehyde and pollute the indoor air. [0003] Formaldehyde is one of the indoor air pollutants, which is highly toxic and irritating, and is extremely harmful to human health. Formaldehyde is easily absorbed by the respiratory tract and gastrointestinal tract due to its high water solubility in water. If the human body is exposed to low-dose formaldehyde for a long time, it can cause chronic...
