Recently, MoO2 has attracted a lot of attention as reforming catalyst for hydrocarbon fuels such as a surrogate of gasoline and jet-A fuel, due to its high resistance to coking, high thermal stability and high sulfur tolerance. However, the phase stability of MoO2 is very limited at the narrow window of O2/C ratio for partial oxidation of hydrocarbon. In this study, various metal (Zr, Ce, Ti, or Co) doped MoO2 spheres were synthesized by ultrasonic spray pyrolysis to enhance the phase stability and redox cycle of the MoO2. Metal doped MoO2 spheres were characterized by XRD, HR-SEM, EDX and BET. To evaluate catalytic activity of doped MoO2 spheres, partial oxidation of n-dodecane as model compound was performed. |
