Title: Supramolecular Engineering of Amorphous Porous Polymers for Rapid Adsorption of Micropollutants and Solar-Powered Volatile Organic Compounds Management Author(s): 이동준; 박치영 Abstract: In this study, a highly efficient molecularly engineered covalent triazine framework (CTF) for rapid adsorption of micropollutants and volatile organic compound (VOC)-intercepting performance using solar distillation is reported. Supramolecular design and mild oxidation of CTFs (CTF-OXs) enable hydrophilic internal channels and improve molecular sieving of micropollutants. CTF-OX shows rapid removal efficiency of micropollutants and can be regenerated several times without performance loss. Additionally, photothermal composite membrane fabrication using CTF-OX exhibits high VOC rejection rate under 1 sun irradiation (1 kW m-2). A prototype of synergistic purification system composed of adsorption and solar-driven membrane can efficiently remove mixed phenol derivatives. This study provides an effective strategy for rapid removal of micropollutants and high VOC rejection via solar-driven evaporation process.

Title: Hybrid Covalent Organic Framework with Carbon Black for High Efficiency Organic Dye Removal and Solar Distillation of Volatile Organic Compounds Author(s): Pancorowati Dhita Azzahra; 박치영 Abstract: Covalent organic frameworks (COFs) are a type of porous crystalline material that emerges with highly ordered and a tunable structures with designer properties. With intrinsic properties like high surface area, adjustable pore size, abundant functional sites, and chemically stable, COFs have been proposed as promising materials for pollutant removal. To gain photothermal effect to this system, we prepared hybrid system of COFs and carbon black (CB), which can harvest a broad range of wavelengths to applied for solar distillation process. Hybrid COFs and CB (CCB) exhibits the ability to remove organic dye molecules and volatile organic compounds (VOCs) via solar-driven evaporation process in water with high efficiency.
