AI Technical Summary

Technical Problem

Existing catalysts are susceptible to corrosion by hydrogen chloride when treating halogen-based VOCs, leading to reduced catalyst activity and structural damage. In particular, precious metal catalysts are expensive and have poor acid resistance.

Method used

Using silicon carbide (SiC) as a support, a composite oxide catalyst of cobalt (Co) and cerium (Ce) is supported to decompose VOCs by heating with electricity, avoiding external heating devices and utilizing the self-heating energy of SiC to decompose VOCs.

Benefits of technology

This achievement enables long-term stability of the catalyst in halogen-based VOC environments, reduces processing costs, facilitates miniaturization of the equipment, and improves the quality of the environment and living environment.
