Methane catalytic abilities are considered to be an important and direct form of experimental evidence for evaluating the efficacy of mixed oxide-ion/electron conductors (MIEC) as anode materials for solid oxide fuel cells (SOFCs) with CH4as the fuel gas. Therefore, a direct link between the quantifiable methane-conversion abilities and CH4-based SOFC electrochemical performance is urgently needed. Here, H2-reduced Sr2ZnMoO6(R-SZMO) as an anode example exhibits excellent catalytic abilities and tolerance to coking when using CH4as the fuel gas, which is dominated by the formation of intrinsic anion-Frenkel defect pairs. DFT calculations reveal that the efficient electron transfer process and optimal selectivity towards CH4conversion are both on the R-SZMO (110) surface. Therefore, applying high CH4activity R-SZMO as the anode catalyst gives excellent anti-carbon deposition performance, high power output, and long-term stability for SOFCs with CH4as the fuel gas.
