ABSTRACT

The research studies the influence of the ratio of initial components on the physicochemical and textural properties in the mechanochemical synthesis of catalysts for carbon monoxide conversion. The catalysts were synthesized using copper, zinc, and aluminum oxides in various percentage ratios as precursors. The specific surface area values were determined. Based on the results of X-ray phase analysis, crystallite sizes were calculated. Correlations between the specific surface area and catalyst composition were identified. Mechanochemical activation and subsequent thermal treatment do not change the phase and elemental composition of the catalysts.

KEYWORDS

Catalyst, carbon monoxide conversion, crystallites, mechanochemical synthesi

Funding

The study was conducted within the framework of a government research assignment. Subject № FZZW-2024-0004.
