 Abstract
In this study, we suggest a facile method to control conditions of single component independently when preparing consisting two-component metal oxides nanofiber by simply dispersing nanoparticles in precursor solution. The well dispersed nanoparticles in nanofibers were successfully synthesized through a simple electrospinning process. The as-synthesized nanodfibers were investigated via FE-SEM, XRD and EDS for structural studies, furthermore, the analysis of UV-VIS and photocatalytic activity were carried out for demonstrate the effect of nanoparticles dispersed in nanofibers. As a result, nanofibres dispersed with nanoparticles have enhanced photocatalytic activity than that of nanofibres only. In this strategy, the introduction of nanoparticles in nanofibers were attribute to enlarge absorption in the visible region (380~440 nm). Additionally, acid sites generated in each metal oxide of Ti and Si increase OH radicals efficiently as well as it limit recombination loss by holding photogenerated electrons for high efficient photocatalytic activity.
