“…The flow rates of reactants were adjusted to obtain an O 2 /C ratio of 0.6. Cuba-Torres et al studied the effect of weight hourly space velocity (WHSV) on the activity of Mo-based catalysts for the partial oxidation of methyl oleate, which showed that the WHSV of 4.2 h À1 leads to the 100% conversion [10]. Therefore, the weight of the catalyst was adjusted to obtain the WHSV of 4.2 h À1 for the present study.…”

“…Since it is produced from biomass, biodiesel does not impose a sulfur poisoning issue for catalytic materials. In the state of Washington, biodiesel is produced mainly from canola and contains almost no sulfur or aromatic compounds, being basically a mixture of methyl esters with methyl oleate as the major component [10]. Based on this compositional analysis, methyl oleate emerges as a suitable model compound for biodiesel.…”

“…Molybdenum oxides are important catalysts, catalytic applications include hydrotreating of oil to reduce the sulphur, nitrogen and aromatics content, yielding cleaner more efficient fuels 6 . MoO 2 is a conductor which has been reported to act as a catalyst in several different reactions including the dehydrogenation of alcohols 7 , the reformation of hydrocarbons 8,9 such as biodiesel 10 and is used for the partial oxidation of aviation fuel 11 . The catalytic activity shown of MoO 2 is due to the transfer of nucleophilic oxygen ions from the oxygen sub-lattice to the catalytically active surface where they are then consumed to sustain the redox cycles 12 .…”

Oxygen adatoms on the MoO 2+ x /Mo(110) surface are observed to be removed when a sufficiently large bias is applied between the scanning tunneling microscope tip and the surface. Experimental observations, such as the bias polarity dependence of adatom removal and the observation of an intermediate state, indicate that the adatom penetrates the surface oxide layer. Through the comparison of finite element method simulations with various experimental relationships, the electric field is concluded to be the sole contributor to adatom penetration into the surface oxide layer. The energetic barrier to this process is estimated to be approximately 0.45 eV in magnitude. Furthermore, the resolution of this phenomenon is on the atomic scale: individual adatoms can undergo surface penetration whilst their nearest neighbour adatoms, separated by 5 Å, are unaffected. The mechanism reported here has the advantages of not strongly influencing the substrate and is exceptionally localised, which can be beneficial for the synthesis of single atom devices.

A SiO 2-supported MoO 2 nanoparticle catalyst was synthesized by a sol-gel method and tested as catalytic material for the partial oxidation of n-dodecane. MoO 2 nanoparticles supported on SiO 2 are < 10 nm in size and show a resistance to sintering at 850 o C, which is a typical reforming temperature for ndodecane. The formation of MoO -Si bonds at the interface between MoO 2 nanoparticles and SiO 2 support appear to be directly related to the enhanced stability to sintering displayed by the nanoparticles. As a result of this particle size stabilization, SiO 2 supported MoO 2 nanoparticles show an improved reforming activity in terms of syngas generation compared to micron-size commercial MoO 2. Thus, commercial MoO 2 exhibits a good initial activity at space velocities up to 15 h-1 , but showing only gas-phase reactions at larger values. Conversely, MoO 2 nanoparticles supported on SiO 2 show a high initial reforming activity (e.g., 69% H 2 yield, 82% CO yield and 100% carbon conversion) even at space velocities up to 30 h-1. Supported MoO 2 nanoparticles also show good stability for the partial oxidation of n-dodecane at 850 o C without any sign of deactivation during the first 24 h on-stream. 10 mol% MoO 2-SiO 2 CO Yield H 2 Yield Conversion MoO 2 10 mol% MoO 2-SiO 2 at WHSV 30 h-1
