Transportation fossil fuels and energy conscience biofuels such as biodiesel are complex fuels that are critical targets for mobile applications of hydrogen generation. Reforming these fuels would not only take advantage of the current fuel distribution infrastructure, but would also provide a proficient use of the fuels if employed in a fuel cell system pre-fed by an external reformer. Nevertheless, current catalysts for fuel reforming such as Pt, Pd, and Rh are not cost effective, and nickel-based catalysts quickly deactivate due to coking, sintering, and sulfur poisoning. This work introduces Mo2C as a catalyst for reforming readily available complex transportation fuels, where current literature is still limited, and compares the partial oxidation (POX) ability of surrogate biodiesel (C19H36O2) and Jet-A fuels using nanoparticle Mo2C synthesized through two different methods: using (NH4)6Mo7O24.4H2O as a precursor, and from MoO2 via in-situ reduction. The latter method uses only MoO2 as the sole precursor without the need of hydrogen feedstock, whereas hydrogen is required using a (NH4)6Mo7O24.4H2O precursor; storage of which is a primary safety concern for onboard mobile applications.
