CeO₂ nanorods, nanocubes, and nanospheres were decorated with 1-4 wt % Ni. The materials were structurally characterized using TEM and <i>in situ</i> XANES/EXAFS. The CO₂ activation was analyzed by DFT and temperature-programmed techniques combined with MS-DRIFTS. Synthesized CeO₂ morphologies expose {111} and {100} terminating facets, varying the strength of the CO₂ interaction and redox properties, which influence the CO₂ activation. Temperature-programmed CO₂ DRIFTS analysis revealed that under hydrogen-lean conditions mono- and bidentate carbonates are hydrogenated to formate intermediates, which deACS applied materials & interfacesCO₂ Activation over Nanoshaped CeO₂ Decorated with Nickel for Low-Temperature Methane Dry Reforming.PMC9305712730872P2-0150823717I-20180898 EC20185092I0-0039P2-0152J7-7294P1-0112J2-1726Lorber KTerzan JDjinovic PZavasnik JLikozar BArcon IHus MfalseCO₂ Activation over Nanoshaped CeO₂ Decorated with Nickel for Low-Temperature Methane Dry Reforming.Dry reforming of methane (DRM) is a promising way to convert methane and carbon dioxide into H₂ and CO (syngas).
