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.

The performance of a chemical reaction is critically dependent on the electronic and/or geometric structures material in heterogeneous catalysis. Over past century, Sabatier principle has already provided conceptual framework for optimal catalyst design by adjusting structure catalytic via change composition. Beyond composition, it essential to recognize that atomic catalyst, encompassing terraces, edges, steps, kinks, and corners, have substantial impact activity selectivity reaction. Crystal-phase engineering capacity bring about alterations configurations enabling control over coordination numbers, morphological features, arrangement surface atoms. Modulating crystallographic phase therefore an important strategy improving stability, activity, materials. Nonetheless, complete understanding how depends crystal remains elusive, primarily due absence molecular-level view active sites across various phases. In this review, we focus assessing dependence phases elucidate challenges complexities inherent catalysis, ultimately aiming improved design.
