Abstract

The invention discloses an integral type room temperature formaldehyde oxidation catalyst and a preparation method thereof, and relates to the fields of catalyst preparation and environmental protection. The integral type room temperature formaldehyde oxidation catalyst takes a supported noble metal catalyst as an active component, takes alkaline substances as a binding agent and an active auxiliary agent, and takes a molded honeycomb carrier as a matrix. The integral type room temperature formaldehyde oxidation catalyst is prepared by mixing the supported noble metal catalyst and the alkaline substances into a solution, then dipping the honeycomb carrier into the solution, and drying at constant temperature. The integral type room temperature formaldehyde oxidation catalyst has higher low-temperature formaldehyde catalytic oxidation activity, and can enable formaldehyde to be converted into harmless H2O and CO2 by means of catalytic oxidation under the condition of not needing other additional devices, thus removing the formaldehyde in an environment-friendly way. The preparation method is simple in technology, fewer in steps and easy to operate, thus being suitable for industrial production.

Description

technical field

[0001] The invention relates to the fields of catalyst preparation and environmental protection, in particular to an integral formaldehyde room temperature oxidation catalyst and a preparation method thereof. Background technique

[0002] Formaldehyde is a colorless gas with a strong pungent smell, and is one of the most serious indoor pollutants. It is widely present in various decoration and decoration materials, and has a long release cycle. Long-term exposure of people will cause headache, dizziness, fatigue, decreased immunity, drowsiness, memory loss, mental depression and other phenomena, and will increase the possibility of cancer. For this reason, formaldehyde has been identified as carcinogenic and teratogenic substances by the World Health Organization. GB50325-2010 "Code for Indoor Environmental Control of Civil Construction Engineering" and "Indoor Air Quality Standard" (GB / T18883-2002) promulgated by China stipulate that the hygienic standard f...
