Hydrogen production from the steam reforming of bio-butanol over novel supported Co-based bimetallic catalysts

► Hydrogen from catalytic steam reforming of bio-butanol. ► Supported Co-based catalysts for steam reforming of butanol and butanol:acetone:ethanol mixture. ► Support influences the behavior of Co-based catalysts in bio-butanol steam reforming. ► Ir addition to Co/ZnO improves its catalytic behavior in bio-butanol steam reforming.
