Abstract

Co-Ag supported on the SiO2 catalyst was synthesized by the sol-gel method and characterized using XRD, FT-IR, TG-DTG, BET, CV, and SEM/EDX analysis. The catalytic performance of the resulting catalyst was examined by the oxidation of mono and sesquiterpenic olefins using hydrogen peroxide and tert-butyl peroxide as oxidant agents. Various parameters such as catalyst amount, temperature, and solvents have been studied. The Co-Ag supported on the SiO2 catalyst showed a high activity, selectivity, and recyclability for the selected oxidation reaction.

Highlights

Solid catalysts are used for converting a vast array of chemicals and fuels, and contribute significantly to economic progress [1, 2]

As part of our ongoing research on the development of new heterogeneous nanocatalytic systems [29] as well as the allylic functionalization of natural terpenes [28, 30], we report the preparation of 1 mol% Co-1 mol% Ag supported on SiO2 by the sol-gel method as a novel catalyst in the oxidation reaction. e physiochemical properties of the prepared catalyst were examined by XRD, FT-IR, TG-DTG, BET, and SEM/EDX analysis
