Contribution of hydrogen bonding to liquid-phase adsorptive removal of hazardous organics with metal-organic framework-based materials

Removing hazardous organics from water or fuel is important for our clean environment; adsorption over porous materials has been a competitive means to eliminate such organics. Here, the adsorption or removal of hazardous organics with metal–organic framework-based adsorbents was explained, especially adsorption that relies on hydrogen bonding (H-bonding). The bonding details (direction, quantitative contribution, importance of 6-membered rings, and characterizations to support H-bonding) and improved performance via H-bonding were investigated. Finally, prospects for further development or research in the relevant fields were suggested.
