Effect of alkali cations on the CuZnOAl2O3 low temperature water gasshift catalyst
(2011)
Low temperature water gasshift catalysts containing 1.0% by weight of alkali elements (Li, K, Rb and Cs) were prepared by impregnation of a ternary Cu/ZnO/Al2O3 (CZA) base catalyst. The calcined precursors
were characterized ...
