Abstract:
For dry reforming of CH4, the effects of defect structure of the surface/subsurface layers of Ce-Zr-La(Ca)-O and Ce-Sm-O nanodispersed fluorites after supporting Pt, Pt+Pd and Pt+Ni+La and their diffusion parameters are considered. For these materials, besides the activation of CH4 on small (1-2 nm) uncovered Pt0 clusters, additional route of both reagents activation is proposed. Complex cluster defect containing Pt δ+/2+ species and interstitial oxygen-isolated anion vacancy pairs facilitates conjugation of CH4 activation and oxygen insertion for CO production. Oxygen diffusion parameters affect the efficiency of this process.
