Facile Synthesis of Highly Active and Robust Ni-Mo Bimetallic Electrocatalyst for Hydrocarbon Oxidation in Solid Oxide Fuel Cells

We report a novel Ni–Mo bimetallic alloy decorated with multimicrocrystals as an efficient anode catalyst for hydrocarbon-fueled solid oxide fuel cells (SOFCs). We show that these Ni–Mo bimetallic alloys are highly active, thermally stable, and sulfur/coke tolerant electrocatalysts for hydrocarbon oxidation. When fueled with CH4–50 ppm of H2S, the SOFC shows a maximum power density of 0.594 W cm–2 at 800 °C. Most significantly, this bimetallic catalyst also offers sustained and steady power output in prolonged tests, suggesting that it is a promising anode catalyst with superior sulfur/coke tolerance and thermal stability.
