Aluminum oxide clusters (AlOCs) possess high surface areas and customizable pore structures, making them applicable in the field of environmental remediation. However, their practical use is hindered by stability issues, aggregation tendencies, and recycling challenges. This study presents an in -situ synthesis of AlOCs on cellulose using a solvent thermal method. The resulting adsorbent's structural and property profiles were thoroughly characterized using multiple analytical techniques. Batch adsorption experiments were performed to assess the adsorbent's capacity and kinetics in removing selected dyes from aqueous solutions. Additionally, both real-environment simulation and regeneration experiments have been conducted to thoroughly assess the adsorbent's reliability, stability, and practical applicability. The aim was to engineer an effective and recyclable adsorbent specifically tailored for dye-contaminated wastewater treatment.

氧化铝簇（AlOCs）具有高表面积和可定制的孔隙结构，使其适用于环境修复领域。然而，它们的实际应用受到稳定性问题、聚集倾向和回收挑战的阻碍。本研究采用溶剂热法在纤维素上原位合成AlOCs。使用多种分析技术对所得吸附剂的结构和性能进行了全面表征。进行了批量吸附实验，以评估吸附剂从水溶液中去除选定染料的能力和动力学。此外，还进行了真实环境模拟和再生实验，以全面评估吸附剂的可靠性、稳定性和实际适用性。目的是设计一种专门为染料污染废水处理量身定制的有效且可回收的吸附剂。
