• produce unsaturated alcohols, suggesting that synergistic Ni–Co interactions played a role in their formation. Keywords: citral hydrogenation; cobalt–nickel mixture; impregnation; ion exchange; natural zeolite; Introduction Numerous publications in the literature highlight zeolites modified with

• offering comparable catalytic properties. Despite extensive research on zeolite-supported transition metal catalysts, their application to citral hydrogenation remains very little explored [11]. Most recent studies focus on the selective hydrogenation of related biomass-derived compounds, such as furfural

• through traditional ion exchange (IE) and impregnation (Imp) processes. Emphasis is put on analyzing the cationic and anionic composition of the materials resulting from both methods and the catalytic performance in citral hydrogenation with a focus on enhancing the formation of unsaturated alcohols
