EFFECTIVE MODIFICATION OF NaX ZEOLITE WITH Ni METAL AND ITS CATALYTIC PERFORMANCE IN OXIDATION OF ETHANOL
Year: 2025
Type: article
Abstract: The presented data showed that the chemical treatment of NaX with Nichel medium resulted in the formation of highly developed hierarchical structures. The esterification of the hydroxyl groups by metal allowed modifying the hydrophobicity of zeolite surface and obtaining truly micro/mesoporous material. The preservation of microporous characteristics was confirmed by XRD and low temperature nitrogen sorption studies. Detailed information on acidic properties of mesoporous titanosilicalites was delivered by IR studies of ethanol oxidation and implicitly from EPR investigations. Well-developed internal microporosity together with the retaining of atoms in tetrahedral framework positions offered higher catalytic activity for the conversion of ethanol molecules than the native microporous of zeolite.
