摘要: 用有机合成乙酰丙酮盐制备CoFe2O4纳米颗粒, 将CoFe2O4纳米颗粒分别与二维过渡金属碳氮化物(MXene)、 氮化碳(C3N4)和粉
末活性炭(AC)复合, 构筑具有磁性功能的复合材料, 用紫外-可见分光光度计分别测量紫外光和可见光照射下4种复合材料罗丹明(RhB)在其吸收峰值处(λ=555 nm)的降解率. 实验结果表明: 获得了基体/负载复合材料, 在强磁作用下可实现光催化剂与液体环境分离; 在紫外光下, 4个样品光催化活性的高低顺序为AC@CFO>MX@CFO>CFO>C3N4@CFO; 在400~780 nm可见光下, 4个样品光催化活性的高低顺序为AC@CFO>C3N4@CFO>CFO>MX@CFO.

关键词: 复合材料, 磁分离, 光催化性能, 降解率

Abstract: CoFe2Onanoparticles were prepared by organic synthesis of acetylacetone salt, CoFe2O4 nanoparticles were compounded with MXene, C3N4 and AC to construct magnetic composites. The degradation rates of rhodamine (RhB) at the absorption peak (λ=555 nm) under ultraviolet (UV) and visible light irradiation were measured by UV-visible spectrophotometer, respectively. The experimental results show that the matrix/load composites are obtained, which can separate the photocatalyst from the liquid environment under strong magnetic action. Under UV light, the order of the photocatalytic activity of the four samples is AC@CFO>MX@CFO>CFO>C3N4@CFO. Under 400—780 nm visible light, the order of photocatalytic activity of the four samples is AC@CFO>C3N4@CFO>CFO>MX@CFO.

Key words: composite, magnetic separation, photocatalytic property, degradation rate
