Abstract

The invention pertains to the technical field of nanometer material preparation and in particular relates to a zirconium dioxide nanometer film with platinum nanocluster and a preparation method and applications thereof. The invention adopts zirconium tetrabutoxide and magnesium ethylate as reaction materials and the nanometer film is formed by a layer by layer formation through a surface sol-gel reaction; the zirconium dioxide film with platinum ion is obtained through acid and alkali treatments and ion exchange. The zirconium dioxide nanometer film with platinum nanometer grain is obtained through a treatment by low temperature hydrogen plasma to the zirconium dioxide film. The size and size distribution of the nanometer grain and the thickness of the film can be designed and controlled by the method of the invention and the product can be used for coating a plane and a curved surface; the low temperature plasma adopted prevents loss of platinum component and damage to the film; the obtained zirconium dioxide nanometer film with platinum nanometer grain is of nanometer crystal film and the platinum nanometer grain shows good thermal stability at high temperature. The technology of the invention can be used for preparing resource-saving high effective coating of vehicle exhaust gas catalytic converter and indoor coating which can catalytically degrade contamination.

Description

technical field

[0001] The invention belongs to the technical field of nanomaterial preparation, and in particular relates to a zirconia nanofilm containing platinum nanoclusters, a preparation method and application thereof. Background technique

[0002] At present, the global ecological environment crisis is becoming more and more serious, and the air pollution and its impact caused by nitrogen oxides are particularly serious. At present, nitrogen oxides mainly come from motor vehicle exhaust, and other pollutants in motor vehicle exhaust also include hydrocarbons and carbon monoxide. With the modernization and urbanization of human life, the use of motor vehicles is becoming more and more popular, and the emission of exhaust gas is increasing. Therefore, the catalytic reaction to eliminate motor vehicle exhaust pollution has become a hotspot of extensive research. Three-way catalyst (TWC) is the best method widely used in the world to control motor vehicle exhaust, whic...
