Description
Technical field
The present invention relates to novel environmental pollution control material field, more particularly to a kind of iron phosphate/manganese phosphate/yttrium phosphate is compound
The preparation method of catalyst.
Background technology
With the development of science and technology, the murder by poisoning organic pollution produced in industrial and agricultural production seriously threatens environment and people
The health of class, seeks a kind of new and effective environmental improvement technology and has great importance.Photocatalysis technology is because of its energy-conservation, height
Effect, contaminant degradation are thorough, non-secondary pollution advantage, have become 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 becomes 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 efficiently visible
Light photocatalysis performance, becomes one of focus of research.
However, the visible-light photocatalysis material that is reported at present is most with higher photo-generated carrier recombination rate and poor
Visible absorption, cause its quantum efficiency relatively low.Therefore, new and effective visible-light photocatalysis material is developed, expands quasiconductor
Material spectrum response range and promotion light induced electron and hole are efficiently separated, and are become current catalysis material research field and are badly in need of
The problem in science of solution.
Content of the invention
The purpose of the present invention is for overcoming the shortcomings of in prior art during photocatalytic pollutant degradation, there is provided a kind of phosphorus
The preparation method of sour ferrum/manganese phosphate/yttrium phosphate composite catalyst.
For this purpose, the invention provides technical scheme below, a kind of system of iron phosphate/manganese phosphate/yttrium phosphate composite catalyst
Preparation Method, in turn includes the following steps：
1) it is 0.1～0.5mol/L ferrous nitrate and by nitre that 5～10mL concentration is 0.1～0.5mol/L by 10mL concentration
Sour yttrium solution mixing, adds 0.2～0.4g manganese dioxide in mixed solution, and being stirred vigorously lower 2～5mL of Deca mass concentrations is
30% H2O2, continue 30～60min of stirring, then 10～15mL of Deca concentration be 0.2～0.8mol/L sodium dihydrogen phosphate thereto
Solution, after 60～100min of stirring, solid is washed with deionized 3～5 times by precipitation, solid-liquid separation, is dried at 105 DEG C；
2) product that obtains will be dried and calcines 5～8h at 400～600 DEG C, you can obtain a kind of iron phosphate/manganese phosphate/
Yttrium phosphate composite catalyst.
The present invention has following superiority：In this process using hydrogen peroxide manganese dioxide reduction simultaneous oxidation iron ion,
Manganese is progressively transformed in solution during reaction by solid, can be formed with the phosphate radical for adding uniform compound
Body.Obtained catalyst has preferable crystal structure and has larger specific surface area, stable, and light degradation treatment effeciency is high.
