Abstract

The invention discloses a preparation method of a green and environment-friendly catalyst for automobile exhaust treatment. The method comprises the steps of surface modification of nano titanium dioxide with dichloropropanol, surface modification of titanium dioxide with quanternary ammonium salt, doping of graphene oxide, ion exchange with a tetraammineplatinum dihydroxide aqueous solution and the like. The invention also discloses the green and environment-friendly catalyst prepared with the preparation method and used for automobile exhaust treatment. The green and environment-friendly catalyst for automobile exhaust treatment is high in nitric oxide removal efficiency and speed, long in service life, green, free of secondary pollution and low in cost.

Description

technical field [0001] The invention relates to the technical field of automobile tail gas treatment, in particular to an environmentally friendly catalyst for removing automobile tail gas and a preparation method thereof. Background technique [0002] In recent years, with the development of the economy and the deepening of people's understanding of improving their own quality of life, the number of cars is increasing. While these cars bring convenience to people's lives, they also inevitably bring about environmental pollution. People also pay a price for their health. One of the main pollutants of automobile exhaust is nitrogen oxides. As a primary pollutant, nitrogen oxides will cause harm to human health. It can irritate people's eyes, nose, throat and lungs, and cause respiratory diseases; the second Pollution can produce photochemical smog, acid rain, greenhouse effect and ozone layer hole effect. Therefore, how to effectively remove nitrogen oxides in automobile ex...
