▎ 摘　　要

NOVELTY - A flue gas denitration catalyst is prepared by introducing cerium into active component iron vanadate. The cerium ion (Ce4+) and cerium ion (Ce3+) are transformed can store and release oxygen. The carrier titanium oxide-graphene has larger specific surface area. The surface of carrier has residual sulfate ion-pre-vulcanization. The graphene has hydrophobic having water and sulfur resisting performance. USE - Flue gas denitration catalyst. ADVANTAGE - The low-temperature flue gas denitration catalyst has high efficiency strong anti-deactivation ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for synthesis method of flue gas denitration catalyst, which involves (i) dissolving tetrabutyl titanate in 40 ml ethanol to form solution (A), mixing graphene oxide powder and 50 ml water, then adding glacial acetic acid to form solution (B), adding solution (B) to the solution (A) to form solution (C), (ii) mixing and stirring the solution (C) for 80-90 minutes, leaving at room temperature for 24 hours, drying and roasting to obtain titanium oxide-graphene sample, and (iii) mixing titanium oxide-graphene sample with iron nitrate nonahydrate, cerium nitrate hexahydrate and 50 ml water to form solution (I), mixing ammonium metavanadate with 50 ml water under stirring at 80 degrees C to form solution (II), adding solution (I) to the solution (II) to form solution (III), continuously stirring for 6-8 hours, adjusting the pH value to aqueous ammonia, washing with water, repeating for 2 times, drying and roasting under nitrogen atmosphere to obtain iron-cerium vanadate/titanium oxide-graphene sample.
