Effective adsorptive removal of indole from model fuel using a metal-organic framework functionalized with amino groups

- Removal of indole from model fuel was firstly studied over MOFs having NH2.
- MOFs with NH2 show much improved adsorption capacity for indole.
- The enhanced adsorption capacity can be explained with H-bonding.
- The MOFs with NH2 group can be used many times by simple washing.
