Structuring Pt/CeO2/Al2O3 WGS catalyst: Introduction of buffer layer

This work is devoted to the development of novel structured catalytic system for WGS reaction. The new concept is related to the presence of a pre-catalytic “buffer” layer formed by WGS-inert oxide, i.e. not involved in CO conversion, but able to increase the number of participating sites in water d...
