| 제목 | Formation and characterization of functionalized amorphous silica nanoparticles with uniform nanopores for removal of heavy metal ions from wastewater |
| 초록 | Silica is a mineral commonly found in nature and has been widely employed in industrial fields. In particular, amorphous silica nanoparticles (ASNs) are one of the most common nanomaterials being used in many applications due to their good biocompatibility, facile synthesis, and relatively easy surface modification and labeling ASNs. We demonstrate highly monodisperse (＜10%) ASNs with the average size range of ~15-300 nm are obtained from our method. Furthermore, our methods allow ASNs can be produced with uniform nanopores of a high specific surface area formed inside the nanoparticles. As-prepared ASNs and nanoporous ASNs have been characterized by various means of materials characterization techniques. These results on the formation and chemical functionalization of ASNs and nanoporous ASNs, as well as use as a means for removing heavy ions from aqueous solutions will be discussed in the presentation. |
