Abstract

Abstract : [RuGa]@NU-1000 shows enhanced adsorption of SO2, specially at low pressures (10 −3 bar) even when compared with other materials employing more expensive precious metals. Abstract : The new material [RuGa]@NU-1000 incorporates Ru and Ga in 1.2 and 1.8 wt% respectively (molar ratio 1 : 2). It stems from the grafting of the heterobimetallic ruthenium gallate complex, [MeRu(η 6 -C6 H6 )(PPh3 )2 ][GaMe2 Cl2 ] into the MOF material NU-1000. [RuGa]@NU-1000 shows enhanced adsorption of SO2, specially at low pressures (10 −3 bar) even when compared with other materials employing more expensive precious metals. Additionally, [RuGa]@NU-1000 samples need not be exposed to such harsh conditions for reactivation as they retain their adsorption properties after several cycles and preserve their porosity and structure. Thus, [RuGa]@NU-1000 is an excellent, selective material suitable for detection and precise quantification of SO2, with a lower cost compared to other MOFs incorporating precious metals.
