| Abstract: | Polymer-supported TiO2 nanofibers with different polyvinylpyrrolidone (PVP)-to-TiO2 (PT) ratios were synthesized and their photocatalytic efficiencies were examined for the decomposition of trichloroethylene (TCE). The spectral results of the TiO2 nanofibers confirmed the presence of TiO2 crystal phases in the nanofibers. The TiO2 nanofiber with the highest PT ratio of 1:1.3 showed the highest TCE decomposition (94%), followed by TiO2 nanofibers with PT ratios of 1:0.7 (91%), 1:0.35 (88%), and 1:0.1 (84%). The conditions of low input concentration and humidity were suggested for the optimal decomposition of TCE. Consequently, the TiO2 nanofiber webs could be used effectively to decompose TCE. |
