Bimetallic Zn and Hf on Silica Catalysts for the Conversion of Ethanol to 1,3-Butadiene

Silica-supported catalysts for the conversion of ethanol to 1,3-butadiene were investigated. The combination of Hf­(IV) and Zn­(II) resulted in a stable, active, and selective catalyst in which the Zn­(II) effectively suppressed the dehydration activity of Hf­(IV); the catalyst preparation method pl...

Description
Summary:Silica-supported catalysts for the conversion of ethanol to 1,3-butadiene were investigated. The combination of Hf­(IV) and Zn­(II) resulted in a stable, active, and selective catalyst in which the Zn­(II) effectively suppressed the dehydration activity of Hf­(IV); the catalyst preparation method plays a crucial role. Using the crystalline Zn-silicate hemimorphite as an alternative Zn­(II) source proved to be even more successful in suppressing ethanol dehydration.
