Abstract

The invention discloses a preparation method of a formaldehyde adsorption-catalytic decomposition composite material. The composite material includes activated carbon and manganese oxide. The preparation method of the formaldehyde adsorption-catalytic decomposition composite material comprises the steps of: (1) obtaining a carbon source and a manganese source, and then mixing the carbon source and the manganese source into raw materials; (2) processing the raw materials, and activating the carbon source into activated carbon The manganese source is converted into manganese oxide during the reaction. In the preparation method of the formaldehyde adsorption-catalytic decomposition composite material of the present invention, firstly, the activated carbon is replaced by an unactivated carbon source, which can greatly reduce the cost; secondly, the process of activating the carbon source into activated carbon and the conversion of manganese source into manganese The process of oxides is carried out synchronously, which can shorten the process and further reduce the cost; since the process of activating the carbon source into activated carbon and the process of converting the manganese source into manganese oxides are carried out synchronously, the activated carbon and manganese in the obtained formaldehyde adsorption-catalytic decomposition composite material are oxidized. stronger binding force.

Description

technical field [0001] The invention relates to the technical field of formaldehyde purification, in particular, to a preparation method of a formaldehyde adsorption-catalytic decomposition composite material. Background technique [0002] Air pollutants are mainly divided into solid pollutants and gaseous pollutants. For solid pollutants in the air (such as PM10, PM2.5) pollution, it is generally removed by physical filtration (that is, to achieve the separation of specific objects by physical means); for gaseous pollutants in the air (such as VOC, that is, organic gaseous substances) , which are generally removed by chemical filtration (that is, using the chemical properties of substances to achieve the separation of specific objects). [0003] Formaldehyde is a gaseous pollutant that is more harmful to the human body. In the removal of formaldehyde by chemical filtration, the use of manganese dioxide in metal oxides as a formaldehyde purification material has been consi...
