| Outline of Final Research Achievements |
The surface area of 0.01wt%Pt/MoO3 reduced at 500℃ depended both on the average Mo valence and the flow rate of H2 in the reduction process. When compared with the surface area at a certain Mo valence, the larger surface area was obtained at the smaller H2 flow rate. A good relationship was seen between the surface area and the pore volume. At the smaller H2 flow rate, the reduction proceeded more slowly, and the formation of Mo metal was restricted, resulting in the porous structure being retained.
The concentration of acid sites on H2-reduced Pt/MoO3 was determined by NH3 temperature-programmed desorption (TPD) and temperature-programmed oxidation of the samples used for NH3-TPD. The acid concentration on MoOx with large surface area was found to be comparable to those on zeolite materials. MoOx was an active and selective catalyst for heptane and cyclopropane isomerization.
