Abstract

The invention discloses a preparation method of a nano silver phosphate photocatalyst, the preparation method comprises the following steps: mixing iron powder with trimesic acid, adding nitric acid and hydrofluoric acid, drying, washing and drying to obtain MIL-100 (Fe); dissolving silver nitrate in deionized water to obtain a silver nitrate solution, and dropwise adding ammonia water to obtain a silver ammonia solution; dissolving disodium hydrogen phosphate dodecahydrate in deionized water, adding molybdenum trioxide, and carrying out ultrasonic treatment to obtain a mixed solution A; dropwise adding a silver-ammonia solution into the mixed solution A, stirring to obtain a mixed precipitate, and washing and drying to obtain a sample B; dissolving the sample B in absolute ethyl alcohol, adding MIL-100 (Fe), and stirring to obtain a mixture C; and putting the mixture C into a drying box, and drying to obtain the nano MIL-100 (Fe), silver molybdate and silver phosphate composite photocatalyst. The photocatalytic degradation performance of silver phosphate is effectively improved, and the prepared composite photocatalyst is high in catalytic activity and stable in catalytic performance.

Description

technical field

[0001] The invention belongs to the technical field of photocatalyst, relates to the preparation technology of photocatalyst, in particular to a preparation method of nanometer silver phosphate photocatalyst. Background technique

[0002] Photocatalyst, also called photocatalyst, can be used to decompose organic compounds, some inorganic compounds, bacteria and viruses. In daily life, photocatalyst can effectively degrade toxic and harmful gases in the air such as formaldehyde, and purify the air efficiently; at the same time, it can effectively kill a variety of bacteria, and can decompose and harmlessly treat the toxins released by bacteria or fungi.

[0003] Silver phosphate is an inorganic substance, soluble in acid, potassium cyanide solution and ammonia water, slightly soluble in water and dilute acetic acid. Because of its strong photooxidation and efficient photocatalytic degradation of organic pollutants, it can be used to make photocatalysts for en...
