摘要

MoO2 microspheres doped with various metal species (Zr, Ti or Co) were simply prepared by means of a one-step ultrasonic spray pyrolysis. The dopant metal species were used as a reducing agent to promote the synthesis of MoO2, which is a metastable phase. The differences in electronegativity and radius between Mo and the dopant metal species influenced the structure and catalytic activity of the resulting MoO2 material. Partial oxidation of n-dodecane, a surrogate of Jet A fuel, was performed to evaluate the catalytic activity of MoO2 spheres doped with Zr, Ti, or Co. Among the produced samples, Co-doped MoO2 microspheres showed the highest H-2 and CO yield as well as the highest C-12 conversion.
