Enhanced adsorption performance of gaseous toluene on defective UiO-66 metal organic framework: Equilibrium and kinetic studies.

•The first report that CTAB-modified UiO-66 was evaluated for toluene vapor adsorption.•The adsorption capacity of CTAB-modified UiO-66 was demonstrated to be 275 mg g−1.•The missing linker defect sites and stronger π-π complexation enhance capture capabilities of modified materials.
