| Popis: | Focused on the separation of photoinduced carriers to improve the photocatalytic performance of semiconductors, polarized C/Bi/Bi2MoO6 were synthesized by electrical polarizing method in presence of organic–inorganic composite films. Significantly, this poling process leads to the better photoactivity for degrade bisphenol A (BPA) and ciprofloxacin (CIP), catalyzing the generation of superoxide radicals (•O2–) and holes (h+) to removal pollutants either through the ferroelectric polarization effect. Meanwhile, the non-destructiveness during the entire polarization process helps maintain the crystal structure and morphology of the catalyst to achieve better photocatalytic performance. This present work not only provides a great route for preparation of various polarized ferroelectric semiconductors, but also indicates the potential of ferroelectric polarization for modification of semiconductors. |
