新材料[RuGa]@NU-1000中Ru和Ga的含量分别为1.2wt%和1.8wt%(摩尔比为1 ： 2)。它源于异质双金属Ru(η_6-C_6H_6)(PPh_3)_2][GaMe_2Cl2]在金属氧化物材料NU-1000中的接枝。[RUGA]@NU-1000表现出对二氧化硫的增强吸附，特别是在低压(10−3 bar)下，即使与使用更昂贵贵金属的其他材料相比也是如此。此外，[Ruga]@NU-1000样品不需要暴露在如此恶劣的条件下进行重新激活，因为它们在几个循环后仍保持其吸附性能，并保持其孔隙度和结构。因此，[Ruga]@NU-1000是一种优良的选择性材料，适用于SO2的检测和精确定量，与其他含有贵金属的MOF相比，成本较低。
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(η6-C6H6)(PPh3)2][GaMe2Cl2] 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.
