摘要

六氟化硫（SF

）因其极强的温室效应和高度的化学惰性，已成为全球减排治理的重点对象。而现有的热催化和光催化等技术普遍存在降解效率低、能耗高等问题。基于溶胶-凝胶法制备了一种新型铈铝复合催化剂（

-AlCeO

），并结合介质阻挡放电（DBD）等离子体技术，实现了对SF

的高效降解。对催化剂物化性质进行了表征，对催化剂

(Al)/

(Ce)（

= 7/1、5/3、3/5和1/7）及DBD输入功率（40~60 W）等关键参数进行了优化，并结合XPS表征解析了等离子体激发下催化剂表面Ce

向Ce

的转化及氧空位的生成机制。结果表明，通过调节

(Al)/

(Ce)及输入功率，可显著增大SF

的降解效率。以Ar为载气、SF

体积分数为1.53%，在输入功率为50 W的条件下，催化剂3/5-AlCeO

展现出较好催化降解性能，降解效率最大为99.8%，产能率为28.99 g/(kW·h)，且连续运行40 min后降解效率依然能保持在99%以上。分析发现，3/5-AlCeO

具备13.08 nm的大孔径和较高的表面氧含量，二者协同DBD产生的高能电子对SF

的预解离作用，促进Ce

介导的氧自由基（·O）攻击S—F键，实现了SF

的深度降解。本研究旨在通过多尺度催化剂设计与等离子体协同激发策略，突破SF

高效低耗降解的技术瓶颈，并阐明其构效关系与反应机理，为相关领域的深入研究提供参考。

Abstract

Sulfur hexafluoride (SF

) has become a key target of global emission reduction efforts due to its extremely strong greenhouse effect and high chemical inertness. However

existing technologies such as thermal catalysis and photocatalysis generally face problems such as low degradation efficiency and high energy consumption. A novel cerium-aluminum composite catalyst (

-AlCeO

) was prepared via the sol-gel method

and combined with dielectric barrier discharge (DBD) plasma technology to achieve efficient degradation of SF

. The physicochemical properties of the catalyst were characterized

and key parameters such as

(Al)/

(Ce) (

= 7/1

5/3

3/5 and 1/7) in the catalyst and the DBD input p

ower (40 W to 60 W) were optimized. Meanwhile

the transformation mechanism of Ce

to Ce

and the generation of oxygen vacancies on the catalyst surface under plasma excitation were analyzed based on XPS characterization. The results show that adjusting

(Al)/

(Ce) and input power could significantly enhance the degradation efficiency of SF

. Under the conditions of using Ar as the carrier gas

the SF

volume fraction of 1.53% and the input power of 50 W

the 3/5-AlCeO

catalyst exhibits excellent catalytic degradation performance

achieving a degradation efficiency of 99.8% and a energy yield of 28.99 g/(kW·h)

and the degradation efficiency remains stable over 99% after continuous operation about 40 min. Analysis reveals that the 3/5-AlCeO

possesses a large pore size of 13.08 nm and abundant surface oxygen

which in synergy with the pre-dissociation effect of high-energy electrons generated by DBD on SF

promotes the Ce

-mediated attack of oxygen radicals (·O) on S—F bonds

thereby achieving deep degradation of SF

. This study aims to overcome the technical bottleneck of efficient and low-energy SF

degradation through multi-scale catalyst design and plasma synergistic excitation strategy

and to clarify the structure-activity relationship and reaction mechanism

providing a reference for related research.
