Our high-efficiency VOC purification catalyst utilizes noble metals (Pt, Pd, Rh) as active components, which are uniformly loaded on a cordierite honeycomb ceramic substrate through nanoscale dispersion technology, combined with a high-surface-area γ-Al₂O₃ coating. It can effectively degrade volatile organic compounds (VOCs) such as benzene series, alcohols, aldehydes, ketones, and esters in industrial exhaust gases. With low ignition temperature, high purification efficiency, long service life, and low energy consumption, this catalyst is an ideal solution for industrial waste gas treatment.
