Hydrogen Production via Steam Reforming of Ethyl Alcohol over PalladiumIndium Oxide Catalyst

الملخص EN

We report the synergetic effect between palladium and indium oxide on hydrogen production in the steam reforming reaction of ethyl alcohol.

The palladium/indium oxide catalyst shows higher hydrogen production rate than indium oxide and palladium.

Palladium/indium oxide affords ketonization of ethyl alcohol with negligible by-product carbon monoxide, while indium oxide mainly affords dehydration of ethyl alcohol, and palladium affords decomposition of ethyl alcohol with large amount of by-product carbon monoxide.

The catalytic feature of palladium/indium oxide can be ascribed to the formation of palladium-indium intermetallic component during the reaction as confirmed by X-ray diffraction and X-ray photoelectron spectroscopic measurements.
