| Abstract: | Acrylonitrile is used as the raw material to synthesize PAN powder,the prepared PAN powder is used to make nanofibers by electrospinning and furthermore,sol-gel method on loading TiO2 be used to prepare TiO2/PAN carbon nanofiber membrane.The nanofiber is characterized by SEM,DG-DTG,element analysis and so on.The study result is that when the concentration of the spinning solution is 3%,the pre-oxidation temperature is 280℃ and carbonization temperature is 550℃,an intact and evenly distributed nanofibers of diameter from 100 nm to 170 nm can be obtained.Under photocatalytic conditions for time of 120 min,the prepared TiO2/PAN carbon nanofibers could biodegrade humic acid on rate of 93%,and its photocatalytic property be better than that of simple suspension type of catalyst with cooperation of TiO2 and carbon nanofiber. |
