Research studies on Metal Organic Frameworks (MOF) based composites and their potential applications in environmental engineering and pollution control have recently emerged. An attractive material to form MOF composites is biochar (BC); a low-cost, highly porous carbonaceous by-product of biomass pyrolysis. This paper presents a critical review on MOF-biochar composites, focusing on fabrication, characterisation, modification, and applications in environmental protection and pollution control. The adsorption mechanisms and influential parameters are systematically examined to develop an insight into interactions between MOF and biochar in remedial process. The adsorption capacity of composites is generally doubled compared to the standalone biochar, while MOFs maintain their crystallinity, even over multiple regeneration cycles, indicating the composites’ long-term applicability and sustainability. These findings highlight the potential of MOF-biochar composites for environmental applications and identify key areas for further research to enhance their sustainability in environmental protection and green energy.

用于环境保护和污染控制的 MOF 生物炭复合材料


最近出现了关于基于金属有机框架 （MOF） 的复合材料及其在环境工程和污染控制中的潜在应用的研究。形成 MOF 复合材料的一种有吸引力的材料是生物炭 （BC）;一种低成本、高度多孔的生物质热解副产品。本文对 MOF 生物炭复合材料进行了批判性综述，重点介绍了 MOF 生物炭复合材料的制备、表征、改性及其在环境保护和污染控制中的应用。系统地研究了吸附机制和影响参数，以深入了解 MOF 和生物炭在修复过程中的相互作用。与独立的生物炭相比，复合材料的吸附能力通常增加了一倍，而 MOF 即使在多个再生循环中也能保持其结晶度，这表明复合材料的长期适用性和可持续性。这些发现突出了 MOF 生物炭复合材料在环境应用方面的潜力，并确定了进一步研究的关键领域，以提高其在环境保护和绿色能源方面的可持续性。
