Hybrid Covalent Organic Framework with Carbon Black for High Efficiency Organic Dye Removal and Solar Distillation of Volatile Organic Compounds

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.
