Efficient Catalytic Elimination of Chlorobenzene Based on the Water Vapor-Promoting Effect within Mn-Based Catalysts: Activity Enhancement and Polychlorinated Byproduct Inhibition

Environmental Science & Technology, Journal Year: 2024, Volume and Issue: 58(8), P. 3985 - 3996

Published: Feb. 15, 2024

Achieving no or low polychlorinated byproduct selectivity is essential for the chlorinated volatile organic compounds (CVOCs) degradation, and positive roles of water vapor may contribute to this goal. Herein, oxidation behaviors chlorobenzene over typical Mn-based catalysts (MnO2 acid-modified MnO2) under dry humid conditions were fully explored. The results showed that presence significantly facilitates deep mineralization restrains formation Cl2 dichlorobenzene. This remarkable vapor-promoting effect was conferred by MnO2 substrate, which could suitably synergize with postconstructed acidic sites, leading good activity, stability, desirable product distribution conditions. A series experiments including isotope-traced (D2O H218O) CB-TPO provided complete insights into direct involvement molecules in reaction attributed root cause proton-rich environment highly reactive water-source oxygen species rather than commonly assumed cleaning hydrogen proton transfer processes (generation active OOH). work demonstrates application potential CVOCs elimination practical (containing vapor) provides guidance development superior industrial catalysts.
