Oxidative coupling reaction of CH4 using oxide ion and electron hole mixed conductive BaCe0.8Gd0.2O3 –α ceramic as a membrane reactor

Abstract

When CH₄ and O₂ are fed into opposite sides of an electrochemical reactor using BaCe_{0. 8}Gd_0.2O_{3 –α} ceramic as a solid oxide membrane, the formation of C₂ hydrocarbons is enhanced by self-short circuiting the reactor owing to oxide ion and electron hole mixed conduction in the ceramic.
