Title
ZSM-5-Ln(Pc)2 catalyzed oxygen oxidation of thiophene
Abstract

Direct oxidative desulfurization of thiophene with oxygen catalyzed by ZSM-5-Ln(Pc)2(NO2)6(NH2)2 (Pc = phthalocyanine) was conducted. The precursor Ln(PcTn)2 (Ln = Ce, Pr, Er, PcTn = tetra-substituted nitro phthalocyanine) was synthesized with programmed heating under nitrogen atmosphere. Then, the precursor was partially reduced by Na2S so the compound Ln(Pc)2(NO2)6(NH2)2 (Ln = Ce, Pr, Er) was obtained, which was then anchored onto ZSM-5 zeolites through the formation of secondary amine. The catalyst was characterized by XRD, SEM, XPS, and N2 adsorption–desorption. For the oxidation of thiophene with oxygen, the catalyst showed remarkable catalytic activity.

► Phthalocyanine-modified ZSM-5 catalysts were prepared. ► Oxygen was chosen as the oxidant for the oxidation of thiophene. ► Reaction kinetics of the catalytic oxidation was investigated. ► Prominent reusability of the catalyst
