| 英文摘要 | Nanomaterials play a crucial role in various areas due to their extraordinary chemical and physical properties. Loading microscopic nanomaterials onto macrostructures is inevitable for their implementation from laboratory experiments to practical applications. Nevertheless, the geometries of conventional supporting structures are usually limited and nanomaterials are easy to be inhomogeneously distributed, aggregated, and lost. Therefore, controllably configuring nanomaterials into sophisticated three-dimensional macroscopic structures without sacrificing their inherent properties remains challenging. Here we utilize the advantages of 3D printing technology to realize this purpose. As a proof-of-concept, the application of 3D stereolithography printed macrostructures containing TiO2 nano particles (TiO2 NPs) for direct adsorption removal of As(III) in water was demonstrated. The morphology and distribution of TiO2 NPs mounted on printed macrostructures were initially characterized. Then batch adsorption experiments were conducted to investigate the effect of the 3D printing process, TiO2 NPs doped concentration and TiO2 NP size as well as adsorption kinetics and isotherms. We also demonstrated that 3D printed adsorption structures could be easily reused over 10 times and were effective for raw arsenic-polluted groundwater samples. Our findings show that 3D printing provides a promising route to design and fabricate customized macrostructures endowed with specific properties of nanomaterials. |
