摘要

在碳峰值和碳中和政策下,以甲苯为代表的芳香族挥发性有机化合物的处理近来受到越来越多的关注。催化氧化法具有效率高、产生二次污染物少的特点,已成为消除甲苯的主流技术。因此,开发高效稳定的催化剂至关重要。本研究综述了不同类型的甲苯氧化催化剂,包括多金属催化剂、高熵催化剂、核壳催化剂以及合成催化剂的后处理技术。此外,还阐述了催化反应机理和催化剂稳定性。在研究的基础上,尝试提出了未来设计新型催化剂的思路,即应重视高熵催化剂以及异质元素的整合、形态调整和表面处理。同时,为深入理解氧化反应机理,必须结合模拟进行操作性或准原位技术研究。在抗中毒研究方面,应考虑更多的有毒物质,这就需要探索新的抗中毒策略和方法,以获得必要的抗中毒能力。所有这些方面都可能促进甲苯催化氧化领域的催化剂开发和催化认识。

Recent advances in catalysts for toluene elimination via catalytic oxidation

Recent advances in catalysts for toluene elimination via catalytic oxidation
Aromatic VOCs, like toluene, have recently attracted increasing attention for the treatment under the carbon peaking and neutrality policy. Catalytic oxidation, characterized by high efficiency and low production of secondary pollutants, has become the mainstream technology for toluene elimination. Thereinto, developing efficient and stable catalysts is essential. This work overviewed different types catalysts for oxidizing toluene, including multi-metal catalysts, high-entropy catalysts, core-shell catalysts, and post-treatment techniques for synthesized catalysts. Additionally, the catalytic reaction mechanisms and catalyst stability were elaborated. Based on the investigations, the ideas for designing novel catalysts in the future were tried to be proposed that the high-entropy catalysts and the integration of heterogeneous elements, morphology adjustment, and surface treatment should be appreciated. Meanwhile, operando or quasi-in situ technology combining with the simulation must be performed for deeply comprehending the oxidation reaction mechanisms. For the investigation of poisoning resistance, one more toxic substance should be considered, which needed to explore new anti-poisoning strategies and methods for essential resistance. All these aspects might promote developing catalyst and understanding catalysis in the field of catalytic oxidation for toluene.
