Change the preparation method of ferrum copper oxide compound phosphoric acid yttrium catalyst.
For this reason, the invention provides technical scheme below, a kind of preparation of ferrum oxide copper oxide compound phosphoric acid yttrium catalyst
Method, in turn includes the following steps：
Adopt one with graphite as negative electrode, metal iron plate and copper sheet are bianode electrolysis bath, with 0.05～0.1mol/L
Sodium carbonate is electrolyte, electrolysis bath Inner electrolysis matter is stirred, and each leads into 1～2A electric current, is passed through after 20min to electrolysis
Add the yttrium nitrate solution being 0.1～0.5mol/L to 5～10mL concentration in groove, then Deca 10～15mL concentration is thereto
0.02～0.08mol/L sodium radio-phosphate,P-32 solution, continuously stirred and electrolysis 2～4h postprecipitation after being added dropwise to complete, solid-liquid separation, by solid
It is washed with deionized 3～5 times, dry at 105 DEG C；Calcine 5～8h by drying the product obtaining at 400～600 DEG C, that is,
Can get a kind of ferrum oxide copper oxide compound phosphoric acid yttrium catalyst.
Compared with traditional catalyst, the present invention has following superiority：Method first with electrolysis forms hydrated ferric oxide.
With Copper hydrate colloid, form hydrated ferric oxide. and Copper hydrate colloidal solid is attached to yttrium phosphate particle surface, formed uniform
Complex, finally calcining forms required catalyst.Obtained catalyst has preferable crystal structure and has larger ratio table
Area, stable, light degradation treatment effeciency is high.
