Purpose The purpose of this paper is to synthesize Cr-ZSM-5 using hydrothermal synthesis in acidic fluoride medium and the investigation of its catalytic performance in heterogeneous oxidation of 2-mercaptobenzothiazole in the presence of H 2 O 2 . Design/methodology/approach The framework was characterized by chemical composition, FT-IR, UV-visible spectroscopy, N 2 adsorption (BET), and diffraction x-ray (DRX). FT-IR spectroscopy shows the characteristic band of Si-O-Cr linkage around 960-990 cm −1 and bands around 688-690 and 627 cm −1 , indicating the presence of extraframework chromium oxide. UV spectra show a shoulder around 244-257 and bands around 360-380 nm, assigning the tetrahedral coordinated environment in (O 2− =Cr 6+ ) − (Cr 5+ -O −1 ), charge transfer transition state (CT) of isolated Cr (VI) inside the structure of Cr-ZSM-5. Findings The catalytic degradation of 2-mercaptobenzothiazole by H 2 O 2 heterogenous oxidation using catalyst Cr-ZSM-5 showed the formation of bis (benzothiazoyl) disulfide with 95 percent yield. Originality/value The application of this process in the environment (catalysis, adsorption, and degradation of organic compounds).
