Description

technical field

[0001] The invention relates to a photocatalyst for degrading nitrogen oxides and a preparation method thereof, belonging to the technical field of catalysts. Background technique

[0002] With the advancement of human science and technology civilization, the industry has been developed on a large scale, and automobiles have become more and more popular, and a large amount of nitrogen oxides have been discharged into the atmosphere. Nitrogen oxides are pollutants of photochemical smog, acid rain, and ozone depletion. Nitrogen oxides have become an urgent problem of air pollution in all countries in the world. The photocatalyst can degrade nitrogen oxides under the action of photocatalysis to generate H 2 O.CO 2 , salt, etc. to achieve harmlessness, thereby purifying the environment.

[0003] TiO 2 Due to the advantages of stable chemical properties, high photocatalytic efficiency, non-toxicity and low price, it has become a more commonly used semiconducto...
