New nanoparticles of NaY, Ni-NaY, and Mn-NaY zeolites: highly efficient catalysts for the oxidation of sulfides to sulfoxides

Abstract

The simple synthesis of NaY, Ni-NaY, and Mn-NaY zeolites nanoparticles was investigated and developed for utilization as efficient catalysts for the oxidation of sulfides to sulfoxides after characterization of the catalyst by XRD, SEM, TGA-DTA, and EDS techniques. The chemical formula of the samples was determined as NaY (Na_0.91AlSi_2.31O₁₁), NiNaY (Ni_0.64Na_0.15AlSi_2.3O11), and MnNaY (Mn_0.5Na_0.15AlSi_2.3O₁₁) using the EDS analysis. The prepared catalyst has suitable potential for the oxidation of sulfides to sulfoxides under mild conditions and was reused 11 times without significant losses in its potential and catalytic activity.
