| Abstract: | The acid-base properties of several NiMoO4 catalysts supported on two silicas and prepared by different methods have been studied by temperature-programmed desorption of NH3. The catalytic behavior in the oxidative dehydrogenation of isobutane for two NiMoO4 catalysts with different acid-base properties are compared. |
| Keywords: | isobutane nickel molybdate oxidative dehydrogenation silica TPD-NH3 |
