Hydrogen consumption in the chemical industry and future global energy challenges have propelled the production of high purity H2 from fossil and renewable resources to the forefront of chemical research. The water-gas shift (WGS) reaction (CO+H2O ? H2+CO2) is one of the most important catalytic processes used in the chemical industry for the production of clean hydrogen. The identification of the active phase and key reaction intermediates is a critical step for determining the reaction mechanism and finding rational ways to improve catalytic activity. Experimentalists and theorists have extensively argued over different mechanisms, likely intermediates and the most probable active sites involved in the WGS reaction.1 From the various proposals, the redox and associative mechanisms are currently the most accepted reaction pathways for the WGS
