硫醇、硫醚等含硫多污染物催化转化行为和降解机理研究进展OA

With the in-depth implementation of China’s 14th Five-Year Plan for ecological and environmental protection,the efficient abatement of sulfur-containing volatile organic compounds(S-VOCs)has become a critical task in air pollution control and the transition toward green and low-carbon development.However,S-VOCs in industrial emissions and environmental matrices typically exist as complex multicomponent mixtures,in which mutual interactions can lead to complicated degradation pathways,uncontrolled by-product formation,and catalyst deactivation,thereby severely limiting the practical effectiveness of existing control technologies under real operating conditions.This review systematically summarized the research progress over the past decade on the catalytic degradation of sulfur-containing multi-pollutant systems,including thiols and thioethers.Particular emphasis was placed on competitive adsorption mechanisms,interfacial reaction pathways,and the regulatory roles of environmental factors.In addition,the performance differences and underlying reaction mechanisms of various catalytic systems for the joint removal of S-VOCs and inorganic sulfur species were comprehensively discussed.Finally,future perspectives were proposed,highlighting that deeper elucidation of the dynamic competitive interactions of multicomponent S-VOCs at catalytic active sites,along with the rational design of catalysts possessing both sulfur-poisoning resistance and selective product transformation capabilities,will be essential to overcoming the current bottlenecks in catalytic efficiency and long-term stability for complex sulfur-containing exhaust streams.
