Recently, the discharge of flue gas has become a global issue due to the rapid development in industrial and anthropogenic activities. Various dry and wet treatment approaches including conventional and hybrid hybrid wet scrubbing have been employing to combat against these toxic exhaust emissions. However, certain issues i.e., large energy consumption, generation of secondary pollutants, low regeneration of scrubbing liquid and high efficieny are hindering their practical applications on industrial level. Despite this, the hybrid wet scrubbing technique (advanced oxidation, ionic-liquids and solid engineered interface hybrid materials based techniques) is gaining great attention because of its low installation costs, simultaneous removal of multi-air pollutants and low energy requirements. However, the lack of understanding about the basic principles and fundamental requirements are great hurdles for its commercial scale application, which is aim of this review article. This review article highlights the recent developments, minimization of GHG, sustainable improvements for the regeneration of used catalyst via green and electron rich donors. It explains, various hybrid wet scrubbing techniques can perform well under mild condition with possible improvements such as development of stable, heterogeneous catalysts, fast and in-situ regeneration for large scale applications. Finally, it discussed recovery of resources i.e., N₂O, NH₃ and N₂, the key challenges about several competitive side products and loss of catalytic activity over time to treat toxic gases via feasible solutions by hybrid wet scrubbing techniques.

近年来，由于工业和人为活动的迅速发展，烟气排放已成为全球性问题。已经采用了各种干法和湿法处理方法，包括常规的和混合的混合湿法洗涤，以对抗这些有毒的废气排放。然而，某些问题，即高能耗，产生二次污染物，洗涤液再生低，效率高，阻碍了它们在工业上的实际应用。尽管如此，由于混合湿法洗涤技术（先进的氧化，离子液体和基于固体工程界面混合材料的技术）因其安装成本低，同时去除多种空气污染物和低能耗而受到了广泛的关注。然而，缺乏对基本原理和基本要求的理解是其商业规模应用的巨大障碍，这是本文的目的。这篇评论文章重点介绍了最近的发展，温室气体的最小化，通过绿色和电子富集的供体再生用过的催化剂的可持续改进。它解释说，各种混合湿法洗涤技术可以在温和条件下表现良好，并可能进行改进，例如开发稳定，多相的催化剂，快速和高效的洗涤。用于大规模应用的原位再生。最后，它讨论了资源的回收，即N ₂ O，NH ₃和N ₂，几种竞争性副产物的主要挑战以及随着时间的流逝，通过混合湿法洗涤技术通过可行的解决方案来处理有毒气体的催化活性的损失。
