摘要
Methyl orange (MO) is a colored dye and hazardous organic pollutant, which poses threats to human health and the environment. Photocatalytic degradation is widely used to remove MO in water because of its high efficiency and no harmful pollution products. The photocatalytic degradation efficiency of titanium dioxide (TiO2) catalysts has been limited by photogenerated electron/-hole recombination. Multi-walled carbon nanotubes (MWCNT) can improve the separation and migration rate of photogenerated electrons. The poly(vinylidene fluoride) (PVDF) membrane with good flexibility, good connectivity and easy recovery, can be selected as carrier material for the photodegradation of MO in water. Here, the hydrophilic TiO2@MWCNT/PVDF membrane was synthesized to photodegrade MO in water and showed excellent pollutant removal efficiency (80%). The novel TiO2@MWCNT/PVDF membrane is a promising photocatalyst for degrading organic pol-lutants in water.
