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 preparation and the pretreatment of Pd/ZnO catalysts were studied for methanol steam reforming. The presence of nitric acid in Pd nitrate precursor significantly altered the porosities and crystalline structures of the ZnO support. The dissolution of ZnO and extent of mixing between the Zn2 + and Pd2 + cations during catalyst preparation may have an impact on the PdZn alloy fo…
