| 논문초록 | Titanium dioxide is well-known as an efficient photocatalyst, but it has decisive shortcoming involved in deficient visible light absorbance, in which only about 10% of sunlight (UV) is available for photocatalysis. Conjugated polymers have emerged as promising candidates for visible-light-driven photocatalytic activity because of their high absorption in UV and visible region via structural tunability and functional diversity. We fabricated organic/inorganic nanocomposite using conjugated polymer dots (CPdots) and mesoporous titania (MT). The CPdots showed high absorption in visible regions; and the MT exhibited absorption in UV region. CPdots@MT had a visible-light-driven catalytic activity because visible-light excited electrons of CPs moved to MT. The transferred electrons in MT were involved in the generation of reactive oxygen species, in which can be used in the applications in dye degradation, organic synthesis, even in micromotioning under visible-light irradiation. |
