摘要: The light response range, reusability, and durability of photocatalyst are the key issues for its practical application. To address these problems, C-doped TiO2/carbon nanofibrous (CTCNF) film with incorporation TiO2 nanoparticles into carbon nanofibers was prepared by electrospinning calcination (pre-oxidation carbonization). All obtained CTCNF films exhibited a promising absorption in ultraviolet–visible region. With optimization carbonization temperature, carbonized at 800 °C (CTCNF-800) showed strongest absorption. Consequently, CTCNF-800 possessed highest photocatalytic degradation efficiency 94.2% rhodamine B. In addition, excellent flexibility deserved mechanical strength, hence, could be easily segregated from solution recycled. Satisfyingly, still exceeded 92% after using six cycles, implying that had reusability well stability. Besides, over 90% kept air without illumination 1 year, indicating outstanding durability. demonstrates tremendous potential application purification wastewater.
