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,
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 focus of research.
However, the visible-light photocatalysis material 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.
The content of the invention
The purpose of the present invention is to overcome the shortcomings of in prior art during photocatalytic pollutant degradation, there is provided a kind of oxygen
Change the preparation method of copper compound phosphoric acid yttrium catalyst.
For this purpose, the invention provides technical scheme below, a kind of preparation method of copper oxide compound phosphoric acid yttrium catalyst, according to
It is secondary to comprise the steps：
Under 60～80 DEG C of water-baths, dripped in the yttrium nitrate solution that 5～10mL concentration is 0.1～0.5mol/L while stirring
Plus 10～15mL concentration is 0.02～0.08mol/L disodium phosphate solns, after 2～4h of stirring, yttrium phosphate little particle is obtained and hangs
Turbid liquid, continues to be added thereto to 0.3～1mmol copper chloride solids, improves bath temperature to 90～100 DEG C, stirs 2-3h, solid-liquid
Separate, solid is washed with deionized 3～5 times, dry at 105 DEG C；The product that drying is obtained is at 400～600 DEG C
5～8h of calcining, you can obtain a kind of copper oxide compound phosphoric acid yttrium catalyst.
Compared with traditional catalyst, the present invention has following superiority：Yttrium phosphate granule is initially formed, then in follow-up mistake
Copper hydrate colloidal solid is formed in journey and is attached to yttrium phosphate surface, form uniform complex.Obtained catalyst have compared with
Good crystal structure and there is larger specific surface area, stable, light degradation treatment effeciency is high.
