Selectivity dependence on the alloying element of carbon supported Pt-alloy catalysts in the hydrogenation of phenol

Single step vapour phase hydrogenation of phenol over Pt-M/C (M = Cr, V and Zr) alloy catalysts was investigated at atmospheric pressure and 200°C. The alloying element shows a significant effect on the product selectivities. While Pt-Cr/C and Pt-V/C catalysts are highly selective for hydrogenation...

Description
Summary:Single step vapour phase hydrogenation of phenol over Pt-M/C (M = Cr, V and Zr) alloy catalysts was investigated at atmospheric pressure and 200°C. The alloying element shows a significant effect on the product selectivities. While Pt-Cr/C and Pt-V/C catalysts are highly selective for hydrogenation of phenol to cyclohexanone, the Pt-Zr/C catalysts are predominantly selective to cyclohexanol.
