Effect of preparation methods of CeO(2) on the properties and performance of Ni/CeO(2) in CO(2) reforming of CH(4)

CO(2) reforming of CH(4) (CRM) is not only beneficial to environmental protection, but also valuable for industrial application. Different CeO(2) supports were prepared to investigate the matching between Ni and CeO(2) over Ni/CeO(2) and its effect on CRM. The physicochemical properties of Ni/CeO(2)...

description CO(2) reforming of CH(4) (CRM) is not only beneficial to environmental protection, but also valuable for industrial application. Different CeO(2) supports were prepared to investigate the matching between Ni and CeO(2) over Ni/CeO(2) and its effect on CRM. The physicochemical properties of Ni/CeO(2)-C (commercial CeO(2)), Ni/CeO(2)-H (hydrothermal method) as well as Ni/CeO(2)-P (precipitation method) were characterized by XRD, N(2) adsorption at − 196 °C, TEM, SEM–EDS, H(2)-TPR, NH(3)-TPD and XPS. Ni(0) with good dispersion and CeO(2) with more oxygen vacancies were obtained on Ni/CeO(2)-H, proving the influence on Ni/CeO(2) catalysts caused by the preparation methods of CeO(2). The initial conversion of both CO(2) and CH(4) of Ni/CeO(2)-H was more than five times that of Ni/CeO(2)-P and Ni/CeO(2)-C. The better matching between Ni and CeO(2) on Ni/CeO(2)-H was the reason for its best catalytic performance in comparison with the Ni/CeO(2)-C and Ni/CeO(2)-P samples.
