The catalytic oxidative coupling of methane (OCM) to C hydrocarbons with oxygen (O -OCM) has garnered renewed worldwide interest in the past decade due to the emergence of enormous new shale gas resources. However, the C selectivity of typical OCM processes is significantly challenged by overoxidation to CO products. Other gaseous reagents such as N O, CO , and S have been investigated to a far lesser extent as alternative, milder oxidants to replace O . Although several authoritative review articles have summarized OCM research progress in depth, recent oxidative coupling developments using alternative oxidants (X-OCM) have not been overviewed in detail. In this perspective, we review and analyze OCM research results reporting the implementation of N O, CO , S , and other non-O oxidants, highlighting the unique chemistries of these systems and their advantages/challenges compared to O -OCM. Current outlook and potential areas for future study are also discussed.
在过去十年中，由于大量新的页岩气资源的出现，甲烷催化氧化偶联制碳氢化合物（OCM）与氧气（O - OCM）在全球范围内重新引起了人们的关注。然而，典型的OCM工艺的碳选择性受到过度氧化生成CO产物的严重挑战。其他气态试剂如N O、CO 、和S作为替代的、较温和的氧化剂来替代O 的研究程度要小得多。尽管有几篇权威综述文章深入总结了OCM的研究进展，但最近使用替代氧化剂（X - OCM）的氧化偶联进展尚未得到详细概述。从这个角度出发，我们回顾并分析了报道N O、CO 、S 和其他非O氧化剂应用的OCM研究结果，突出了这些体系独特的化学性质以及与O - OCM相比它们的优势/挑战。还讨论了当前的前景和未来研究的潜在领域。
