Abstract

A novel nano-sized Pt/ZnO catalyst has been prepared by impregnating 1 wt% Pt on a nano-sized ZnO supports, with spherical and rod-type morphology and tested for the water gas shift reaction at a gas hourly space velocity of 9,583 h -1. The Pt/ZnO catalyst with spherical ZnO morphology exhibited an almost thermodynamic equilibrium CO conversion value of 70 % at 400°C with 100 % CO 2 selectivity. The high activity/stability of the catalyst is due to a good interfacial contact between Pt and ZnO.
