摘要

锰基材料因其低成本和出色的氧化还原性能而被广泛用作催化去除气态污染物的催化剂。然而,活性和稳定性不理想等现有挑战阻碍了锰基催化剂的应用。将锰基材料封闭在特定区域有可能影响分子间排列和质量扩散,降低活化能势垒,从而提高反应稳定性和催化剂活性。在这篇重要综述中,我们简要总结了常见的用于消除气态污染物(包括氮氧化物和挥发性有机化合物)的纳米封闭锰基类似物。文中还详细介绍了常见的封闭催化剂宿主及其对催化行为的影响,并对相关机理进行了深入探讨。通过这篇评论性综述,我们旨在提高研究人员对使用封闭催化作为基本指导甚至工具来提高消除气态污染物的催化性能的关注。

Confined Manganese-Based Catalysts for Gaseous Pollutant Removal: A Critical Review

Confined Manganese-Based Catalysts for Gaseous Pollutant Removal: A Critical Review

Manganese-based materials are widely applied as catalysts for catalytic removal of gaseous pollutants due to their low cost and excellent redox performance. However, existing challenges such as unsatisfactory activity and stability hinder the application of manganese-based catalysts. Confining manganese-based materials into specific regions has the potential to influence intermolecular arrangement and mass diffusion and lower the activation energy barrier, thereby enhancing reaction stability and the catalyst’s activity. In this critical review, we briefly summarize the common reported nanoconfined manganese-based analogues for gaseous pollutant elimination including nitrogen oxides (NOx) and volatile organic compounds (VOCs). Details of the commonly reported hosts for confined catalysts and their impact on catalytic behavior and an in-depth discussion of the related mechanism are included. Through this critical review, we aim to raise the research attention on using confined catalysis as a fundamental guide or even tool to improve the catalytic performance of gaseous pollutant elimination.

期刊介绍: ACS ES&T Engineering publishes impactful research and review articles across all realms of environmental technology and engineering, employing a rigorous peer-review process. As a specialized journal, it aims to provide an international platform for research and innovation, inviting contributions on materials technologies, processes, data analytics, and engineering systems that can effectively manage, protect, and remediate air, water, and soil quality, as well as treat wastes and recover resources. The journal encourages research that supports informed decision-making within complex engineered systems and is grounded in mechanistic science and analytics, describing intricate environmental engineering systems. It considers papers presenting novel advancements, spanning from laboratory discovery to field-based application. However, case or demonstration studies lacking significant scientific advancements and technological innovations are not within its scope. Contributions containing experimental and/or theoretical methods, rooted in engineering principles and integrated with knowledge from other disciplines, are welcomed.
