摘要为了解决TiO2难以响应太阳光的问题，本实验采用了上转换发光剂复合材料的方法对TiO2光催化进行了改性。制备上转换发光剂和TiO2粉体都成粉末状，在降解有机污染溶液体系中难以回收，并对降解水域体系造成二次污染，本实验采用活性炭纤维(ACF)负载上转换发光剂形成复合材料，对催化材料进行固定，与此同时活性炭纤维自身也有吸附有机污染物的功能，这样就解决了光催化剂难回收，实现了吸附剂的原位再生。课题对实验所制备的ACF负载上转换发光剂复合材料进行表征，并对其光降解性能，稳定性等进行评估。通过降解亚甲基蓝溶液，改变环境影响因素，探究ACF负载上转换发光剂复合材料具体的降解性能，回收利用率等。44989

Title Preparation and Photocatalytic Degradation about Upconversion
Agent and Carbon Fiber Material Supported Research
Abstract
To solve the problem of TiO2 is difficult to respond to the sunlight, the present study, this experiment adopted the method of upconversion luminescence agent composite of TiO2 photocatalytic. Preparation of the upconversion luminescence agent and TiO2 are powder, they are difficult to recover in the degradation of organic pollution solution system and may have secondary pollution.ln this experiment, actives carbon fiber(ACF) was used to support conversion luminescent agent. It loaded up catalytic material. At the same time, activated carbon fiber also has the function of adsorption of organic pollutants, this would resolve the photocatalyst that is difficult to recycle. The regeneration of adsorbent was realized. The ACF loading up conversion luminescent agent composite was characterized. and evaluate the performance and stability of the optical degradation. By degradation of methylene blue solution, changing environmental factors, to explore the luminescent agent composite material of carbon fiber-conversion load of concrete degradation and recycling utilization.
