Recently, MoO2 has attracted a lot of attention as reforming catalyst for hydrocarbons 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. Ti4+ has been used as a dopant to improve stability of MoO2. In this study, macroporous Ti doped MoO2 powders were directly produced by ultrasonic spray pyrolysis using polystyrene (PS) beads as templates. Macroporous Ti-MoO2 powders were characterized by XRD, HR-SEM, EDX and BET. To evaluate catalytic activity of macroporous Ti-MoO2 powders, partial oxidation of n-dodecane was performed. |
