Organic sulfur gases (COS, CS₂ and CH₃SH) are widely present in reducing industrial off-gases, and these substances pose difficulties for the recovery of carbon monoxide and other gases. The reaction pathways and reaction mechanisms of organic sulfur on different catalyst surfaces have yet to be fully summarized. The literature shows that many factors, such as catalyst synthesis method, loaded metal composition, number of surface hydroxyl groups, number of acid-base sites and methods of surface modification, have important effects on the catalytic performance of metal catalysts. Therefore, this paper presents a comprehensive review of the research on the application of catalysts such as zeolites, metal oxides, carbon-based materials, and hydrotalcite-like derivatives in the field of organic sulfur removal. Future research prospects are summarized, more in situ characterization experiments and theoretical calculations are needed for the catalytic decomposition of methanethiol to analyze the coke generation pathways at the microscopic level, while the simultaneous removal of multiple organic sulfur gases needs to be focused on. Based on previous catalyst research, we propose possible innovations in catalyst design, desulfurization technology and organic sulfur resource utilization technology.

有机硫气体（COS、CS ₂和 CH ₃SH) 广泛存在于减少工业废气中，这些物质给一氧化碳和其他气体的回收带来了困难。有机硫在不同催化剂表面的反应途径和反应机理尚待全面总结。文献表明，催化剂合成方法、负载金属组成、表面羟基数目、酸碱位数目和表面改性方法等诸多因素对金属催化剂的催化性能有重要影响。因此，本文对沸石、金属氧化物、碳基材料、类水滑石衍生物等催化剂在有机硫脱除领域的应用研究进行了全面综述。对未来的研究前景进行了总结，甲硫醇催化分解需要更多的原位表征实验和理论计算，从微观层面分析生焦途径，同时需要关注多种有机硫气体的同时脱除。在前人催化剂研究的基础上，我们提出了催化剂设计、脱硫技术和有机硫资源化利用技术的可能创新。
