| titleOfInvention | Bi plasma modified strontium bismuth tantalate photocatalyst and preparation method thereof |
| abstract | The invention provides a Bi plasma modified strontium bismuth tantalate photocatalyst and a preparation method thereof, belonging to the field of photocatalysis. The preparation method comprises the following steps: (1) bi (NO) 3 ) 3 ·5H 2 Uniformly dispersing O in NaOH solution to obtain a mixture A; (2) ta 2 O 5 And SrCl 2 ·6H 2 Uniformly dispersing O in NaOH solution to obtain a mixture B; (3) dropwise adding the mixture B into the mixture A, adding a NaOH solution, adding a reducing agent, and uniformly dispersing to obtain a mixture C; (4) and reacting the mixture C for 18-72 h at the temperature of 200-250 ℃, cooling, washing and drying to obtain the catalyst. The catalyst has a unique perovskite layered structure and surface Bi plasma modification, and expands the light absorption range of NO photocatalytic oxidation reaction to a visible light region. The preparation process of the catalyst is simple and easy to implementThe synthesized material has high phase purity, and can efficiently remove low-concentration NO at ppb level. |
