Abstract

This study explores the hydrothermal synthesis and characterization of novel, green, reusable aluminium metal–organic aerogels (Al-MOAs) designed for wastewater treatment. Using aluminium nitrate nonahydrate as metal precursor, glutaric acid and phloroglucinol as organic linkers, two aluminium metal–organic aerogels [Al-MOA (1) and Al-MOA (2)] were synthesized followed by thermal. The successful synthesis of aerogels was confirmed via IR, FE-SEM, EDX, and powder XRD analyses. The FE-SEM analysis revealed microporous surface favorable for Victoria blue dye adsorption and catalytic applications in phenol degradation. The effects of key parameters such as pH, time, and the concentration of Al-MOA (1) and (2) on dye adsorption efficiency were studied. The Al-MOAs also demonstrated catalytic efficiencies in phenol degradation indicating potential in wastewater treatment. Optimal adsorption efficiency was observed at 3 pH demonstrating 99% dye removal by Al-MOA (1). Additionally, in dye adsorption, Al-MOA (1) and (2) highlighting the potential for multiple reuse cycles, thus offering a sustainable, green, cost-effective approach towards wastewater treatment. This study contributes to the development of advanced, non-toxic, insoluble, reusable, sustainable solutions for wastewater treatment utilizing metal–organic aerogels.

绿色、可重复使用、高效的铝基金属有机气凝胶用于废水处理

本研究探索了新型、绿色、可重复使用的铝金属有机气凝胶（Al-MOAs）的水热合成和表征。以非水合硝酸铝为金属前驱体，戊二酸和间苯三酚为有机连接剂，热合成了两种铝金属有机气凝胶[Al-MOA(1)和Al-MOA(2)]。通过IR， FE-SEM， EDX和粉末XRD分析证实了气凝胶的成功合成。FE-SEM分析表明微孔表面有利于维多利亚蓝染料的吸附和苯酚降解的催化应用。考察了pH、时间、Al-MOA(1)、(2)浓度等关键参数对染料吸附效率的影响。Al-MOAs还显示了苯酚降解的催化效率，表明其在废水处理中的潜力。在3 pH条件下，Al-MOA的最佳吸附效率为99%(1)。此外，在染料吸附方面，Al-MOA(1)和(2)强调了多次重复使用循环的潜力，从而为废水处理提供了可持续、绿色、经济的方法。这项研究有助于开发先进的、无毒的、不溶的、可重复使用的、可持续的金属有机气凝胶废水处理解决方案。图形抽象
