Catalytic partial oxidation of methane over oxide-ion-conductive lanthanum silicate apatites.

A lanthanum silicate LaSiO (LSO) crystallizes in an apatite-type structure and has been known as a promising oxide-ion conductor. Here, we report the activity of LSO for catalytic partial oxidation of methane (CPOX) to synthesis gas. The LSO catalyst demonstrated relatively high catalytic activity from 500 to 700 °C, with CH conversion reaching 22.
