| titleOfInvention | A gadolinium chromate/silver/silver phosphate composite photocatalyst and its application in VOCs purification |
| abstract | The invention discloses a gadolinium chromate/silver/silver phosphate composite photocatalyst and its application in VOCs purification. The composite photocatalyst is expressed as GdCrO 3 /Ag/Ag 3 PO 4 . The preparation method is as follows: 1) take gadolinium source and chromium source in a mortar according to the ratio of 1:1, add an appropriate amount of urea, grind evenly, and then calcine in a specific atmosphere at high temperature to obtain gadolinium chromate; 2) in chromic acid The gadolinium is loaded with silver particles to obtain a gadolinium chromate/silver composite; 3) silver phosphate is loaded on the gadolinium chromate/silver to obtain a gadolinium chromate/silver/silver phosphate composite. The elemental Ag in the GdCrO 3 /Ag/Ag 3 PO 4 prepared by the invention undergoes plasmon resonance under the excitation of visible light to generate hot electron-hole pairs. The hot electron-hole pair connects the gap - separated semiconductors GdCrO3 and Ag3PO4 without sacrificing their oxidation or reduction potential, thereby enhancing the photocatalytic redox ability of the composite. GdCrO 3 /Ag/Ag 3 PO 4 was used for photocatalytic degradation of organic pollutants. It fully catalyzes the purification of typical organic gas pollutants such as toluene, xylene and benzene under visible light irradiation and mild reaction conditions, such as 90 o C. |
