NOx treatment’s photocatalytic activity using the Ag/SnO2/polypropylene

Abstract

Environmental and materials scientists are becoming more interested in catalytic materials for use in filtration and remediation of contaminated gas.. In this study, Ag/SnO₂ catalysts were adorned onto a polypropylene (PP) membrane to eliminate nitrogen oxide (NO_x) gas. The catalyst-coated membrane achieved an efficiency of 63.62% and exhibited a low generation of nitrogen dioxide (NO₂), just 2.51%. It is noteworthy that even after five cycle experiments, the Ag/SnO₂/PP catalytic membrane showed remarkable resilience, retaining a high removal efficiency of approximately 58.2%. Furthermore, the catalytic membrane demonstrated a positive trend in transforming NO_x into eco-friendly products, hence decreasing the generation of NO₂ byproducts. These encouraging findings demonstrate the Ag/SnO₂ catalysts' potential for treating contaminated gasses in the near future in catalytic membrane technologies.
