Molybdenum carbide catalysts stability

In accordance with HRTEM data, molybdenum in the catalyst under test is stabilized as two different forms. The first form is characterized by the molybdenum concentration on the zeolite surface in the form of 2-10 nm particles observed by an electron microscope (Fig. 2a) and recorded in EDX spectra. Microdiffraction of electrons allows this form to be identified as a crystalline phase of M02C carbide. Also, the agglomeration of the particles of this form is observed in the catalyst, leading to the generation of large microblock M02C formations up to 50 nm in size.
