Promoting effect of Zr on the catalytic combustion of methane over Pd/γ-Al

Hongbo NA,Tianle ZHU,Zhiming LIU,Yifei SUN

Frontiers of Environmental Science & Engineering 2014, Volume 8, Issue 5,   Pages 659-665 doi: 10.1007/s11783-013-0613-1

Abstract: The effect of Zr on the catalytic performance of Pd/γ-Al O for the methane combustion was investigatedThe results show that the addition of Zr can improve the activity and stability of Pd/γ-Al O catalystwhich, based on the catalyst characterization (N adsorption, XRD, CO-Chemisorption, XPS, CH -TPR and O-TPO), is ascribed to the interaction between Pd and Zr.Zr addition inhibits Pd aggregation and enhances the redox properties of active phase Pd / Pd .

Frontiers of Environmental Science & Engineering 2017, Volume 11, Issue 6, doi: 10.1007/s11783-017-0976-9

Abstract: Three types of catalysts, Pt/BaO/Al O , Pt/Pd mechanical mixing catalyst (Pt/BaO/Al O +Pd/Al O ) andPt-Pd co-impregnation catalyst (Pt-Pd/BaO/Al O ) were prepared by incipient wetness impregnation methodCompared with Pt/BaO/Al O , (Pt/BaO/Al O +Pd/Al O ) produced less N O and more NH during NO storageand reduction process, while an opposite trend was found over (Pt-Pd/BaO/Al O +Al O ).Most of N O formed over (Pt-Pd/BaO/Al O +Al O ) was originated from Pd/BaO/Al O component.
