Abstract ▼ AI-Helper

Ru catalysts supported on $CeO_2$ were synthesized by an impregnation method and characterized by numerous analytical techniques including X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), transmission electron microscopy (TEM), and scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDS). Upon utilization of these catalysts for methane dry reforming with a $CH_4/CO_2$ ratio of 1:1 at different temperatures ranging from 550 to $750^{\circ}C$, the $Ru/CeO_2$ catalysts have shown to be active. In particular, Ru(0.55wt%) supported on $CeO_2$ (1) prepared by a hydrothermal method exhibited excellent activity with the conversion of > 75% at $750^{\circ}C$. In addition, the catalyst also proved to be highly stable for at least 47 h without catalyst deactivation under the dry reforming conditions.

대상 데이터

Two types of ceria supports, CeO₂ (1) and CeO₂ (2) were employed in this study. CeO₂ (1) was synthesized by a conventional method while CeO₂ (2) was prepared using MCM-48 as a template, producing mesoporous ceria.

이론/모형

Ruthenium metals were then loaded onto the CeO₂ supports using an impregnation method. SEM analysis showed that the Ru contents were in the ranges of 0.
To introduce Ru metals onto the as-synthesized CeO₂ materials, an impregnation method was employed. In a typical experiment, the mixture of RuCl₃·6H₂O and either CeO₂(1) or CeO₂(2) were dispersed in D.
