| titleOfInvention | A kind of preparation method of magnesium ferrite/silver phosphate composite photocatalyst |
| abstract | The present invention discloses a kind of preparation method of magnesium ferrite/silver phosphate composite photocatalyst, concrete steps are as follows: 1) be under agitation that to be added drop-wise to 50 ~ 100mL concentration be in the sodium hydroxide solution of 0.1 ~ 0.2mol/L for the silver nitrate of 0.2 ~ 0.4mol/L by 50 ~ 100mL concentration, after separation of supernatant, obtain silver oxide particle; Add to silver oxide particle the ammonia spirit that 30 ~ 50mL concentration is 20% ~ 25% (mass percentage concentration), be stirred to silver oxide and dissolve completely, generate silver-colored ammonia complexing solution; 0.4 ~ 0.6mol ferric nitrate and 0.2 ~ 0.3mol magnesium nitrate is added in silver-colored ammonia complexing solution, after stirring 3 ~ 4h, add 0.02 ~ 0.03mol sodium dihydrogen phosphate wherein, continue stirring 2 ~ 3h, filter and 3 ~ 4 washings, then dry at 110 ~ 120 DEG C, after drying at 500 ~ 600 DEG C roasting 5 ~ 6h, obtain a kind of magnesium ferrite/silver phosphate composite photocatalyst with after stove cooling.This building-up process is simple, and silver orthophosphate and magnesium ferrite close contact, be conducive to the transition of light induced electron, avoid compound, is conducive to improving catalytic efficiency. |
