Catalyst formulations containing Group 11 metals for hydrogen generation

A method for producing a hydrogen-rich gas which comprises:

• contacting CO-containing gas with a water gas shift catalyst in the presence of water at a temperature of not more than about 450° C.,
• wherein the water gas shift catalyst comprises:
• a) Rh, its oxides or mixtures thereof;
• b) Pt, its oxides or mixtures thereof;
• and
• c) Ag, its oxides or mixtures thereof wherein the water gas shift catalyst contains between about 0.01 wt. % and about 10 wt. % Fe whenever Fe is present in the water gas shift catalyst.

A catalyst for catalyzing the water gas shift reaction comprising:

• at least one member selected from the group consisting of Rh, Ni, Pt, their oxides and mixtures thereof;
• at least one member selected from the group consisting of Cu, Ag, Au, their oxides and mixtures thereof;
• and
• at least one member selected from the group consisting of K, Cs, Sc, Y, Ti, Zr, V, Mo, Re, Fe, Ru, Co, Ir, Pd, Cd, In, Ge, Sn, Pb, Sb, Te, La, Ce, Pr, Nd, Sm, Eu, their oxides and mixtures thereof, and
• wherein the catalyst contains between about 0.01 wt. % and about 10 wt. % Fe whenever Fe is present in the catalyst.
