The invention discloses a kind of method that Template synthesis has loose structure nickel ferrite based magnetic loaded visible light catalyst, concretely comprise the following steps：With alkaline solution treatment 1~8h of cotton fiber that molar concentration is 1~4mol/L, then in 60~120 DEG C of dryings；Treated cotton fiber is immersed in 3~8h in the colloidal sol of ferric nitrate, nickel nitrate and citric acid formation, then dried in 60~120 DEG C to gel；Gel is warming up to 400~800 DEG C of calcining 3h with 1~5 DEG C/min heating rate in temperature programming stove, room temperature is cooled to the furnace and the nickel ferrite based magnetic loaded with loose structure is made.The present invention is using cotton fiber as the NiFe of templated synthesis 2 O 4 With loose structure, cotton fiber template belongs to plant template, will not cause secondary pollution to environment；And cotton fiber template contral NiFe 2 O 4 Loose structure and pattern, the loose structure improves NiFe 2 O 4 Photocatalysis performance. |
