Promoting Effect of Cerium Oxide on the Catalytic Performance of Yttrium Oxide for Oxidative Coupling of Methane.

The promoting effect of CeO on the catalytic performance of YO, which is moderately active catalyst, for the oxidative coupling of methane (OCM) reaction was investigated. The addition of CeO into YO by coprecipitation method caused a significant increase in not only CH conversion but also C (CH/CH) selectivity in the OCM reaction. C yield at 750 °C was increased from 5.
