Abstract. Our recent work demonstrated that Cu–Pd bimetallic catalyst supported on a nano-crystalline CeO2 synthesized by urea gelation method is effective for oxygen-assisted water–gas shift (OWGS) reaction. The present study focuses on the roles of Cu and Pd in CuPd/CeO2 bimetallic catalysts containing 20–30 wt% Cu and 0.5–1 wt% Pd used in the OWGS reaction employing a combined bu…
Abstract. The effect of Zn addition on the Pd turnover rate (TOR) for the water–gas shift (WGS) reaction was studied on 2 wt% Pd on alumina with Zn content varying from 0 to 19% Zn by weight. Over 85% of the Zn reacted with alumina to form zinc aluminate with a fraction reacting with Pd. The average Pd– Zn coordination number as measured by extended X-ray absorption fine structure (EXAF…
