Perspective outlines a subprocess-level framework for chloride effects in catalytic ozonation, highlighting pathways to improve mechanistic interpretation in saline water treatment.
Chloride (Cl ‒ ) exerts complex and condition-dependent effects in heterogeneous catalytic ozonation (HCO), yet current mechanistic interpretations remain fragmented and often lack direct evidence. This Perspective rethinks Cl ‒ effects across ozone availability, interfacial accessibility, and oxidation pathway regulation, while considering complexities under realistic saline conditions. A roadmap integrating comprehensive performance assessment, subprocess-specific validation, and application-oriented evaluation is proposed to enable more reliable interpretation of Cl ‒ effects.
