Petrochemical, tobacco, and pharmaceutical processing industries extensively use chlorinated volatile organic compounds (CVOCs) as solvents and lubricants, which cause significant environmental hazards. Zeolite is a highly efficient catalytic material for low-temperature degradation of CVOCs, with strong practical applications in industry. In this study, we used chlorobenzene (CB) as a model pollutant to introduce two innovative modified zeolites: a hollow zeolite-supported CuO catalyst (CuO/Z-HO) and an
