Catalysis by a ruthenium complex heterogenized in faujasite-type zeolites: the water gas-shift reaction
Abstract
The Ru(NH3)63+ complex, exchanged as such in faujasite-type zeolites, can be converted into another kind of complex of the form [Ru(NH3)x(OH)y(CO)z]n+ with n < 3; this complex has no homogeneous equivalent, it is stable up to 280 °C, is a very active catalyst for the water gas-shift reaction, and it exceeds the activity of a commercial copper based low-temperature shift catalyst.
