Nitrous oxide (N2O) decomposition is increasingly acknowledged as a viable strategy for mitigating greenhouse gas emissions and addressing ozone depletion, aligning significantly with the UN's sustainable development goals (SDGs) and carbon neutrality objectives. To enhance efficiency in treatment and explore potential valorization, recent developments have introduced novel N2O reduction catalysts and pathways. Despite these advancements, a comprehensive and comparative review is absent. In this review, we undertake a thorough evaluation of N2O treatment technologies from a holistic perspective. First, we summarize and update the recent progress in thermal decomposition, direct catalytic decomposition (deN2O), and selective catalytic reduction of N2O. The scope extends to the catalytic activity of emerging catalysts, including nanostructured materials and single-atom catalysts. Furthermore, we present a detailed account of the mechanisms and applications of room-temperature techniques characterized by low energy consumption and sustainable merits, including photocatalytic and electrocatalytic N2O reduction. This article also underscores the extensive and effective utilization of N2O resources in chemical synthesis scenarios, providing potential avenues for future resource reuse. This review provides an accessible theoretical foundation and a panoramic vision for practical N2O emission controls.

一氧化二氮分解与增值的进展与挑战
一氧化二氮 (N 2 O) 分解越来越被认为是减少温室气体排放和解决臭氧消耗的可行策略，与联合国可持续发展目标 (SDG) 和碳中和目标高度一致。为了提高处理效率并探索潜在的增值，最近的发展引入了新型 N 2 O 还原催化剂和途径。尽管取得了这些进步，但缺乏全面和比较的审查。在本次综述中，我们从整体角度对 N 2 O 处理技术进行了全面评估。首先，我们总结并更新了N 2 O的热分解、直接催化分解（deN 2 O）和选择性催化还原方面的最新进展。范围延伸到新兴催化剂的催化活性，包括纳米结构材料和单原子催化剂。此外，我们还详细介绍了具有低能耗和可持续优点的室温技术的机理和应用，包括光催化和电催化N 2 O还原。本文还强调了N 2 O资源在化学合成场景中的广泛有效利用，为未来的资源再利用提供了潜在的途径。这篇综述为实际的 N 2 O 排放控制提供了易于理解的理论基础和全景视野。
