摘　　要：基于TiO_(2)主体材料,通过镱掺杂改性制备了Yb-TiO_(2)纳米光催化剂,并用XRD、FT-IR和PL等技术对样品的晶体结构和性能进行表征,优化了Yb-TiO_(2)纳米光催化剂配比(0.8%),并以玫瑰红B模拟废水进行探针反应,分别在紫外光和可见光照下评价其光催化性能。与未掺杂TiO_(2)纳米光催化剂进行对比,Yb-TiO_(2)纳米光催化剂对玫瑰红B溶液表现出更高的光催化降解性能,在紫外光(90 min)和可见光(180 min)下的脱色率分别达到99%和90%。The Yb-TiO_(2) nano-photocatalysts were prepared by ytterbium doped modification which based on TiO_(2) as the main material,and the crystal structure and properties of the samples were characterized by XRD,FT-IR,and PL.The proportion of Yb-TiO_(2) nano-photocatalyst(0.8%)was optimized,rose red B was used to simulate organic wastewater as the probe reaction,and the photocatalytic performance was evaluated under ultraviolet and visible light,respectively.Compared with the unadulterated TiO_(2) nano-photocatalyst,the Yb-TiO_(2) nano-photocatalyst exhibited higher photocatalytic degradation performance for rose red B solution,with a decolorization rate of 99% and 90% under ultraviolet and visible light,respectively.
