High Coke-Resistance Pt/Mg(1-x)Ni(x)O Catalyst for Dry Reforming of Methane

A highly active and stable nano structured Pt/Mg(1-x)Ni(x)O catalysts was developed by a simple co-precipitation method. The obtained Pt/Mg(1-x)Ni(x)O catalyst exhibited cubic structure nanocatalyst with a size of 50–80 nm and realized CH(4) and CO(2) conversions as high as 98% at 900°C with excellent stability in the dry reforming of methane. The characterization of catalyst was performed using various kinds of analytical techniques including XRD, BET, XRF, TPR-H(2), TGA, TEM, FESEM, FT-IR, and XPS analyses. Characterization of spent catalyst further confirms that Pt/Mg(1-x)Ni(x)O catalyst has high coke-resistance for dry reforming. Thus, the catalyst demonstrated in this study, offers a promising catalyst for resolving the dilemma between dispersion and reducibility of supported metal, as well as activity and stability during high temperature reactions.
