| titleOfInvention | A kind of preparation method of hollow structure yttrium phosphate catalyst |
| abstract | The present invention discloses a kind of preparation method of hollow structure yttrium phosphate catalyst, in turn includes the following steps: cetyl trimethylammonium bromide is dissolved in hexamethylene system, add yttrium nitrate solution, be vigorously stirred to form microemulsion；It is the Fluorinse of 0.1~0.5mol/L into microemulsion that 10mL concentration is added dropwise under continuous stirring, increasingly generates borontrifluoride yttrium, is separated by solid-liquid separation, after cleaning 4~6 times with dehydrated alcohol and deionized water respectively, drying obtains borontrifluoride yttrium nano particle；Borontrifluoride yttrium nano particle is added in 20mL water, dibastic sodium phosphate solution is added dropwise thereto, the mole of dibastic sodium phosphate is 1.1~1.2 times of the mole of yttrium nitrate used, after being added dropwise to complete, using heating water bath to 70~80 DEG C, 10~16h is kept, obtained solid passes through washing and drying, a kind of hollow structure yttrium phosphate catalyst can be obtained.Obtained catalyst has preferable crystal structure and has biggish specific surface area, stablizes, and light degradation treatment effeciency is high. |
