- Abstract:
- Heterogeneous catalytic ozonation (HCO) has emerged as a research hotspot due to its high efficiency in pollutant degradation. However, its development and application are constrained by challenges such as low density of active catalytic sites and inefficient ozone mass transfer. Single-atom catalysts (SACs), characterized by maximized atomic utilization, unique electronic configurations, and uniformly distributed active sites, offer a promising solution for optimizing ozone activation pathways. This review presents recent advances in SACs applied to HCO systems, analyzing the impact of synthesis strategies—including atomic layer deposition (ALD), pyrolysis, and wet-chemical methods—on their catalytic performance. We elucidate the structure-activity relationships between SACs’ coordination environment (e.g., central metal species, loading, and substrate materials) and their efficacy in ozone activation and pollutant degradation. Furthermore, the adsorption-activation mechanisms of ozone on SACs surfaces are systematically deciphered, providing theoretical and technical insights for precisely regulating catalytic activity and stability.
