- 摘要:
- 非均相催化臭氧氧化(HCO)技术因其高效降解污染物的能力成为研究热点,但其发展与应用受限于催化剂活性位点密度低与臭氧传质效率不足等问题。单原子催化剂(SACs)因其高原子利用率、独特的电子结构和均匀的活性位点分布,为优化臭氧活化路径提供了新的方案。介绍了SACs在HCO体系中的研究进展,解析了原子层沉积、热解及湿化学法等不同SACs制备方法对其催化性能的影响,阐明其配位环境(中心原子种类、负载量及基质材料)对O3活化与污染物降解效能的构效关系,并揭示O3在SACs表面的吸附-活化机制,为精准调控SACs催化活性与稳定性提供理论与技术支撑。
- 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.
