บทคัดย่อ

Preparation of cellulose acetate (CA)/TiO2/WO3 composite nanofibers via sol-gel with electrospinning process for improving the photocatalytic efficiency was conducted. CA was removed from fibers by a heat treatment. Microstructure and elemental composition of TiO2/WO3 nanofibers were evaluated by scanning electron microscope (SEM) and energy dispersive microscopy (EDX), respectively. The results showed that the nanofibers of TiO2 and WO3 were achieved with the average diameter range of ca. 310-701 nm and both TiO2 and WO3 are well dispersed along fiber length, confirmed by an EDX analysis. The results also showed that the smoothness of fiber surface decreased with decreasing WO3 contents. The photocatalytic activity of the materials were also tested for methylene blue degradation. TiO2/WO3 exhibited the highest activity comparing to pure TiO2 and WO3. Moreover, it was found that a TiO2/WO3 specimen possessed the energy storage ability as a result, it showed the photocatalytic activity in the absence of light. ฉ 2017 Trans Tech Publications, Switzerland.
