Description
Technical field
The present invention relates to novel environmental pollution control material field, more particularly to a kind of preparation side of phosphomolybdic acid Mn catalyst
Method.
Background technology
With the development of science and technology, caused murder by poisoning organic pollution serious threat environment and people in industrial and agricultural production
The health of class, seek a kind of new and effective environmental improvement technology and have great importance.Photocatalysis technology is because of its energy-conservation, height
Effect, contaminant degradation are thorough, non-secondary pollution advantage, turn into a kind of emerging environmental improvement with important application prospect at present
Technology.In recent years, the development of new and effective visible-light photocatalyst turns into an important research content in photocatalysis technology,
Wherein there is the catalysis material of surface plasma resonance effect, because of its unique Surface Physical Chemistry property and efficient visible
Light photocatalysis performance, turns into one of focus of research.
The anion of 12 hetropoly acids is one kind 1:12A type heteropolyacid anions, 1826 first by Bei Cailiwu
This finds.This kind of 1:The structure of 12A types is measured by Keggin first, therefore frequently referred to structure with Keggin.Its basic structural unit
It is four groups of three molybdenum oxygen octahedras, three molybdenum oxygen octahedras share the oxygen atom on drift angle in each group, and phosphorus atoms are located at four
The center in face body cave.Due to its special structure so that the material has special property.But phosphomolybdic acid manganese does not have related report so far
Road.
The content of the invention
The purpose of the present invention is for overcome the deficiencies in the prior art, there is provided a kind of preparation method of phosphomolybdic acid Mn catalyst.
The technical solution adopted by the present invention is in turn include the following steps：
5g ammonium molybdates are dissolved in the dust technology that 100~500mL mass percentage concentrations are 10%~30%, under agitation
Instill the phosphoric acid that 20~80mL concentration is 2~5mol/L dropwise, add after the completion of 2~3g manganese chlorides continue stirring 10~
20min, all reactants are transferred in the hydrothermal reaction kettle of polytetrafluoroethylsubstrate substrate, be put into baking oven at 160~180 DEG C
Natural cooling after 18~24h of reaction, solids is obtained after centrifugation and washs, dry by deionized water, that is, obtains a kind of phosphomolybdic acid
