Abstract

A SiO2-supported MoO2 nanoparticle catalyst was synthesized by a sol-gel method and tested as catalytic material for the partial oxidation of n-dodecane. MoO2 nanoparticles supported on SiO2 are °C, which is a typical reforming temperature for n-dodecane. The formation of Mo O Si bonds at the interface between MoO2 nanoparticles and SiO2 support appear to be responsible for the enhanced stability to sintering displayed by the nanoparticles. As a result of this particle size stabilization, SiO2 supported MoO2 nanoparticles show an improved reforming activity in terms of syngas generation compared to micron-size commercial MoO2. Thus, commercial MoO2 exhibits a good initial activity at space velocities up to 15 h−1, but showing only gas-phase reactions at larger values. Conversely, MoO2 nanoparticles supported on SiO2 show a high initial reforming activity (e.g., 69% H2 yield, 82% CO yield and 100% carbon conversion) even at space velocities up to 30 h−1. Supported MoO2 nanoparticles also show good stability for the partial oxidation of n-dodecane at 850 ◦C without any sign of deactivation during the first 24 h on-stream.
