摘要
Low mass-transfer efficiency and reaction-driving force make it difficult to realize thorough purification in traditional low-concentration pollutant treatments. Herein, we propose an "adsorption/catalysis in situ" perylene based bifunctional micelle for efficient, accurate and rapid adsorption and catalytic degradation of low-concentration bisphenol A (BPA). They show super-fast (within 10 s), high capacity (448 mg g-1 ) and selectivity for BPA adsorption, due to π-π, hydrophobic interactions and hydrogen bonding. The BPA degradation efficiency improves by up to 8 times after forming micelles compared with simple perylene nanorods, which is primarily due to the superior mass-transfer from adsorption. Moreover, self-assembly can optimize the stacking of the perylene moieties and facilitate charge transfer in micelle, and the regular π-π stacking of inside perylene units enhances the response to visible light, resulting in high catalytic capacity and good cycling stability.
