Technology.In recent years, the development of new and effective visible-light photocatalyst becomes an important research content in photocatalysis technology,
The wherein catalysis material with surface plasma resonance effect, because of its unique Surface Physical Chemistry property and efficient visible
Light photocatalysis performance, becomes one of hot spot of research.
However, the visible-light photocatalysis material reported at present has higher photo-generated carrier recombination rate and poor mostly
Visible absorption, cause its quantum efficiency relatively low.Therefore, new and effective visible-light photocatalysis material is developed, semiconductor is expanded
Material spectrum response range and promotion light induced electron and hole efficiently separate, and become current catalysis material research field and are badly in need of
The problem in science of solution.
Invention content
During to overcome the shortcomings of photocatalytic pollutant degradation in the prior art, a kind of phosphorus is provided
The preparation method of sour yttrium/silver orthophosphate composite catalyst.
For this purpose, the present invention provides following technical scheme, a kind of preparation method of yttrium phosphate/silver orthophosphate composite catalyst,
It in turn includes the following steps：
1) it is 15%~25% 3~6mL mass fractions to be added dropwise in the yttrium nitrate solution of a concentration of 0.2~0.3mol/L of 5mL
Ammonium hydroxide, obtain yttrium hydroxide colloidal solution；
2) disodium phosphate soln 1 of the silver nitrate solution 1mL and a concentration of 20mmol/L of a concentration of 20mmol/L are measured
~10mL is mixed under 350~400 revs/min of rotating speed, persistently stirs 3~4h, and it is molten to generate silver orthophosphate formation yellow green colloid
Liquid；
3) obtained yellow green colloidal solution and yttrium hydroxide colloidal solution are mixed into 20~30min under continuous stirring,
The sodium dihydrogen phosphate for adding a concentration of 0.2~0.3mol/L of 5-8mL continues to stir 3h, precipitate, is separated by solid-liquid separation, spends
Ion water washing 3~5 times, is dried at 100~105 DEG C, obtains yttrium phosphate/silver orthophosphate composite catalyst.
Compared with traditional catalyst, the present invention has following superiority：(band is just for yttrium hydroxide colloidal solution during being somebody's turn to do
Electricity) and yellow green phosphoric acid silver colloidal solution it is (negatively charged) it is electrically charged on the contrary, colloidal solid be combined with each other under electrostatic interaction,
Even dispersion.Yttrium hydroxide generates yttrium phosphate under the conditions of having existing for hydrogen phosphate.Obtained catalyst has preferable crystal
Structure is stablized, and light degradation treatment effeciency is high.
