Coumarin-functionalized metal–organic frameworks: adsorbents with photo-responsive active sites for adsorptive desulfurization

Abstract

Photo-responsive metal-organic frameworks (PMOFs) have great potentials in on-demand controllable adsorption processes under distinct light conditions, which is challenging to realize by conventional adsorbents with static frameworks and properties. Here...

Synergistic Boosting Capture Ability of Thiophene Sulfur with a Novel Dual-Amino-Functionalized MOF-on-MOF Adsorbent

“…To date, fossil fuels are still the main source of energy in the world, where burning of sulfur-containing compounds converts them into sulfur oxides. These emissions are extremely harmful to human health, prone to respiratory diseases and cause various environmental hazards, including air and water pollution. − Metal–organic frameworks (MOFs) are a kind of inorganic–organic hybrid porous crystalline materials with a high specific surface area, high porosity, and abundant active sites. − As emerging materials for a wide range of applications, MOFs are also favored in the field of fuel adsorption and desulfurization, which especially contain Zn, Cu, Co, Ni, and Cr, − such as Cu-BTC . However, under actual working conditions, the application environment of MOF adsorbents such as deep desulfurization of water-containing fuel oil, requires a certain degree of water resistance, so their water stability has attracted a lot of attention. , There are three general types of water-stabilized MOFs.…”
