Abstract
The pretreatment of Fechral support for preparing a methane pyrolysis catalyst was studied. The Fechral support after high-temperature (1000°C) treatment in air was examined by atomic force microscopy, scanning electron microscopy with chemical analysis, and X-ray phase analysis of the surface layer. The morphological, chemical, and phase changes on the support surface were studied. A mechanism of formation of the dispersed α-Al2O3 phase on the Fechral surface was suggested.
