Cerium Ion Doped Tungsten Trioxide Catalyst and Preparation Method and Application

The invention discloses a cerium ion doped tungsten trioxide catalyst and a preparation method and application thereof and belongs to the technical field of catalysts.

The preparation method of the cerium ion doped tungsten trioxide catalyst comprises the steps of (A), adding tungsten powder into H2O2 which is subjected to magnetic stirring at the speed of 200-300r/min; (B), adding cerous nitrate into CH3CH2OH which is subjected to magnetic stirring at the speed of 150-200r/min; (3) adding yellow sol-like matters obtained in the step (A) into the solution obtained in the step (B), heating the mixture with stirring, and aging the mixture; (D) placing the gel obtained in the step (C) into a drying oven to perform drying at the temperature of 100-105 DEG C, and grinding the dried gel into powder; and (E), placing the powder obtained in the step (D) into a muffle furnace, heating the powder, and calcining the powder to obtain the cerium ion doped tungsten trioxide catalyst.

The cerium ion doped tungsten trioxide catalyst produced by the preparation method is good in stability, high in activity, simple in preparation, low in cost, convenient to operate and not liable to cause secondary pollution.
