Description
Technical Field
The invention relates to a honeycomb material supported transition metal oxide catalyst and a preparation method thereof, belonging to the technical field of indoor air purification and catalysis.
Background
Formaldehyde is the most common volatile organic pollutant in daily life, and is listed as a first carcinogen by the international agency for research on cancer (IARC) in 2004. Along with the continuous development of economy in China, the housing level of people is remarkably improved, architectural decorative paint and artificial wood are used on a large scale, the architectural decorative paint and the artificial wood become important sources of indoor formaldehyde, convenience is brought to life of people, and meanwhile, health hidden dangers are increased. The release period of formaldehyde in a room is long, the formaldehyde is generally released for 3-15 years, skin and respiratory tract can be stimulated when the formaldehyde is contacted with high concentration, symptoms such as eye pain, cough and dyspnea can be caused, and canceration can be caused by long-term contact. Therefore, there is an urgent need for effective and practical techniques to eliminate indoor formaldehyde pollution, improve air quality and reduce public health risks.
Currently, the formaldehyde elimination method can be mainly divided into three aspects: source control, ventilation and terminal treatment. The method for eliminating formaldehyde by oxidation of the metal catalyst is one of important methods in terminal treatment, and is characterized in that formaldehyde adsorbed on the surface of the metal catalyst can be decomposed into carbon dioxide and water by the catalytic action of the metal catalyst, so that the method has the characteristics of high removal efficiency, stability and the like. Noble metal catalysts (platinum, gold, palladium, silver) have excellent formaldehyde removal performance, but noble metal catalysts are expensive and difficult to popularize and apply. In addition to noble metal catalysts, transition metal (iron, manganese, copper, chromium, etc.) oxides also have oxidation activity on formaldehyde, are relatively inexpensive, have enhanced potential for catalytic activity, become a research hotspot of recent interest, and are widely applied to formaldehyde removal research.
The transition metal catalyst is generally present in the form of particles, and the catalyst particles need to be loaded during application to avoid catalyst loss and secondary pollution. The catalyst can be bonded to the carrier by means of chemical bonds, but the catalyst particles are easily exfoliated by using this method and the calcination process needs to be complicated at high temperature. The catalyst is immobilized on the carrier by using the binder, so that higher loading strength can be obtained, catalyst particles are not easy to fall off, the carrier does not need high temperature resistance, and the catalyst can be immobilized at lower temperature, but reaction sites are reduced due to the fact that the catalyst particles are wrapped by the binder, so that the catalyst loaded by using the binder faces the problem of low formaldehyde removal rate. Therefore, the development of a material for efficiently removing formaldehyde has high practical significance.
