Effect of size and morphology of chromium(III) oxide nanoparticles on their catalytic properties in deep oxidation of methane

  • Published:
Theoretical and Experimental Chemistry Aims and scope

We have shown that the activity of catalysts based on Cr2O3 in deep oxidation of methane is determined by both the sizes of the crystallites and their morphology. In the temperature range up to 450 °C, we observe the appearance of a size effect: an increase in the specific catalytic activity of the chromium oxide as its particle size decreases. Formation of chromium oxide on the surface of Al2O3 increases the dispersity of the active component and increases the thermal stability of the catalyst.
