Biomass-based adsorbents have emerged as attractive materials for the adsorptive removal of gaseous pollutants due to their abundance in nature, low cost, and environmental friendliness. The modification of the adsorbent surfaces has been regarded as an intriguing technique for improving and enhancing their adsorption capacity for efficient removal of pollutants. The present study investigates the most recent developments and applications of biomass-derived adsorbents for removing various gaseous contaminants from air and gas streams. The use of biomass materials such as agricultural waste and wood residue to synthesize adsorbents provides a long-term solution to environmental pollution. This is due to the fact that biomass-derived adsorbents can be designed to have a large surface area, porosity, and surface functionality, thereby increasing their adsorption capacity and selectivity for target pollutants using a variety of chemical processes such as carbonization, activation, and modification. This study presents a comprehensive report on the use of biomass-based adsorbents for the removal of various gaseous pollutants such as carbon dioxide (CO), volatile organic compounds (VOCs), nitrogen oxides (NO ), sulfur dioxide (SO), hydrogen sulphide (HS) and multi-gas components. The surface chemistry of biomass adsorbents, in addition to their porous nature, is discussed. Multi-gas adsorption properties and the regeneration of biomass adsorbent are also discussed. The challenges and future prospects for developing biomass-based adsorbents for gaseous pollutant removal are also discussed, emphasizing the importance of a thorough understanding of adsorption mechanisms, scalability of manufacturing processes, and integration with existing air purification technologies. The findings of this study present biomass-derived adsorbents as a promising alternative for mitigating the challenges associated with the danger of gaseous pollutants, contributing to sustainable environmental management and public health protection.
基于生物质的吸附剂因其在自然界中储量丰富、成本低且环境友好，已成为用于吸附去除气态污染物的有吸引力的材料。吸附剂表面的改性被视为一种有趣的技术，可用于改善和提高其吸附能力，以有效去除污染物。本研究调查了生物质衍生吸附剂在从空气和气流中去除各种气态污染物方面的最新进展和应用。利用农业废弃物和木材残渣等生物质材料合成吸附剂为环境污染提供了一种长期解决方案。这是因为生物质衍生吸附剂可以设计成具有大的表面积、孔隙率和表面官能团，从而通过碳化、活化和改性等各种化学过程提高其对目标污染物的吸附能力和选择性。本研究全面报告了基于生物质的吸附剂用于去除各种气态污染物的情况，如一氧化碳（CO）、挥发性有机化合物（VOCs）、氮氧化物（NO ）、二氧化硫（SO）、硫化氢（HS）和多气体成分。除了其多孔性质外，还讨论了生物质吸附剂的表面化学。还讨论了多气体吸附性能和生物质吸附剂的再生。还讨论了开发用于去除气态污染物的生物质基吸附剂所面临的挑战和未来前景，强调了深入了解吸附机制、制造工艺可扩展性以及与现有空气净化技术整合的重要性。本研究结果表明，生物质衍生吸附剂是应对气态污染物危害相关挑战的一种有前途的替代方案，有助于可持续环境管理和公共卫生保护。
