When the formaldehyde reaches a certain concentration indoors, people feel uncomfortable, 0.08m3The formaldehyde concentration can cause redness, itching, discomfort or pain in the throat, hoarseness, sneezing, chest distress, asthma, dermatitis, etc. Chronic exposure to formaldehyde increases the chances of developing particular cancers such as hodgkin's lymphoma, multiple myeloma, and myeloid leukemia. The methods for removing formaldehyde which are commonly used at present comprise the following methods: firstly, activated carbon is used for adsorbing formaldehyde, but the adsorption capacity of the activated carbon is very limited, and the more the capacity of the activated carbon is after one monthThe weaker the come and the weaker; secondly, the ventilation method is also a method for eliminating formaldehyde, which is the simplest method, but the method has the defects that the release period of the formaldehyde is longer, generally about three to fifteen years, and obviously cannot meet the use requirement of people; thirdly, the air purifier is used for eliminating formaldehyde, the air purifier only plays a role in assisting and remedying, and under the condition that indoor air is polluted, the pollution can be reduced to a certain degree by using the air purifier, but the pollutant left in the air by the formaldehyde can not be eliminated fundamentally; and fourthly, formaldehyde scavengers are used, the method is based on chemical reaction, the target substance is substantially reduced in toxicity or is converted into a nontoxic substance, formaldehyde can be oxidized into formic acid and can also be reduced into methanol, the toxicity and the irritation of the two substances are lower than those of formaldehyde, but the toxicity still exists, for example, certain formaldehyde scavengers with strong oxidation can oxidize the formaldehyde but are easily decomposed, the formaldehyde is directly damaged by spraying on the wood board, and the formaldehyde scavenger loses the efficacy within a few hours. The methods have the defects that the formaldehyde pollution cannot be solved quickly and fundamentally, at present, a plurality of researches are carried out to oxidize and reduce the formaldehyde into water and carbon dioxide by adopting a catalyst, the method is high in speed and can radically eliminate the formaldehyde, but the catalysts used at present are mostly noble metal materials, the cost is too high, the consumption of common people cannot be started, and therefore, a novel cheap catalytic formaldehyde removal product is urgently needed.
