This study developed a novel composite material containing cellulose nanocrystals (CNCs) and HKUST-1. Here, the addition of CNCs was used to enhance the characteristics of HKUST-1 in terms of surface area, adsorption ability, and functional groups. Here, the fabrication of CNCs@HKUST-1 composites was carried out by adding CNCs into the fabrication process of HKUST-1. The addition of CNCs provides additional functional groups on the surface of composite material which can be used to attach other organic compounds, such as in waste management and drug delivery systems. Here, CNCs@HKUST-1 composites were tested as a material for crystal violet (CV) removal and doxorubicin (DOX) loading. The removal capacity of CNCs@HKUST-1 composite towards CV molecules reached 1182.25 ± 27.74 mg/g, while the loading capacity for DOX drugs was around 1514.94 ± 11.67 mg/g. Both applications showed that CNCs@HKUST-1 composite had higher adsorption capacity and ability compared to its precursor materials, i.e., CNCs and HKUST-1.
本研究开发了一种包含纤维素纳米晶体（CNCs）和HKUST-1的新型复合材料。在此，添加CNCs用于增强HKUST-1在表面积、吸附能力和官能团方面的特性。在此，通过将CNCs添加到HKUST-1的制备过程中来制备CNCs@HKUST-1复合材料。CNCs的添加在复合材料表面提供了额外的官能团，可用于连接其他有机化合物，如在废物管理和药物递送系统中。在此，对CNCs@HKUST-1复合材料作为去除结晶紫（CV）和负载阿霉素（DOX）的材料进行了测试。CNCs@HKUST-1复合材料对CV分子的去除能力达到1182.25±27.74mg/g，而对DOX药物的负载能力约为1514.94±11.67mg/g。这两种应用均表明，CNCs@HKUST-1复合材料与其前体材料（即CNCs和HKUST-1）相比具有更高的吸附容量和能力。
