Catalyst surfaces with tunable hydrophilicity and hydrophobicity: metal-organic frameworks toward controllable catalytic selectivity

This report describes a facile strategy that has the capability of adjusting different surface hydrophilicities/hydrophobicities of catalysts by covering metal-organic frameworks with graphene oxide and reduced graphene oxide. The catalysts exhibit remarkable catalytic selective performance for the hydrogenation of different hydrophobic and hydrophilic reactants. MOFs with controllable wettability are obtained by tuning the reduction degree of graphene oxide which display additional catalytic selectivity.
