Coating sponge with multifunctional and porous metal-organic framework for oil spill remediation

It is worth to synthesize high-efficient sorbents for oil spill on ocean or rivers due to its fatal influence on marine life as well as human beings. This article introduced a highly hydrophobic and oleophilic composite material (MS-CMC-HPU-13) consists of water-stable porous Metal-Organic Framework (MOF) crystals and melamine sponge (MS). This specified composite material exhibited excellent recoverable and recyclable absorption performance of oil and organic solvents. The oil adsorption capacity of MS-CMC-HPU-13 can reach up to 13,000%, proving its potential ability to clean up oil spill. Besides, an oil collecting device assembled by MS-CMC-HPU-13, pipe and self-suction pump is constructed, which can collect oil continuously from the water surface with high speed under harsh conditions.
