Correlation between catalytic activity and support reducibility in the CO 2 reforming of methane over Pt / Ce x Zr 1 − x O 2 catalysts

We have investigated the relationship between the reducibility of the support and the catalytic activity of supported Pt on a series of catalysts supported on ceria–zirconia mixed oxides. The supports were prepared by co-precipitation with varying Ce/Zr ratios. X-ray diffraction analysis indicated that, depending on the Ce/Zr ratio, solid solutions of cubic… (More)
