| 논문초록 | TiO2 is a wide band gap semiconductor and can only absorb UV light, resulting in its inefficient utilization of solar energy. For an optimized utilization of solar energy, combining TiO2 with other semiconductors to form heterojunctions is an effective way of enhancing photocatalytic activity by inducing visible light absorption. We fabricated a visible-light-driven photocatalyst through chemical bonding between TiO2 and semiconducting conjugated polymer (CP). The interfacial chemical bonding between TiO2 and CP can act as a pathway quickly transfer the excited electrons from CP to conduction band of TiO2, which significantly increases the photocatalytic efficiency. Furthermore, the photocatalyst can convert the hydrophobicity of the surface to hydrophilic by modifying the CP on the photocatalyst surface. This wettability conversion of the photocatalyst surface allows the photocatalyst to be used with high efficiency both water and organic solvent. |
