| titleOfInvention | Preparation and protection method of magnetic near-infrared light composite photocatalyst |
| abstract | The invention belongs to the field of photocatalytic materials, and particularly relates to a magnetic near-infrared composite catalyst (beta-NaYF) 4 :Yb 3+ ,Tm 3+ /TiO 2 /Fe 3 O 4 @SiO 2 ) And a method for preparing the same. Respectively adopting a hydrothermal method and a solvothermal method to prepare an up-conversion luminescent material beta-NaYF 4 :Yb 3+ ,Tm 3+ And magnetic substance Fe 3 O 4 And then beta-NaYF using a modified baby method 4 :Yb 3+ ,Tm 3+ Degussa P25 and Fe 3 O 4 The magnetic near-infrared composite catalyst is prepared by wrapping the silicon dioxide layer. The composite catalyst utilizes an up-conversion material to absorb near infrared light for conversion to emit ultraviolet light, and TiO is excited 2 The photocatalytic activity realizes the utilization of near infrared light, and improves the utilization efficiency of the infrared spectrum area of sunlight in photocatalytic reaction. In addition, the photocatalyst is endowed with magnetism, magnetic separation and recycling can be realized, the treatment cost is reduced, and the economic benefit is improved. The invention can be applied to photocatalysis environment treatmentThe field of physics. |
