Boosting water activation determining-step in WGS reaction on structured catalyst by Mo-doping

• Mo- Eu-doped ZrO 2 acts as proton conductor increasing the WGS catalyst’ activity. • The structuration of the catalyst leads to higher conversions. • Structured catalysts demonstrate the promoter effect is caused by proton conductor. • Promoted WGS catalysts very promising for H 2 technology mobile devices. Proton conductors Mo-Eu-Zr mixed oxide systems were synthesized and further mixed with a conventional Pt/CeO 2 /Al 2 O 3 catalyst to...
