Abstract:
Cellulose is the most abundant natural polymer and, as a result of its renewability, abundance, low cost and fascinating structure and properties, is being investigated to produce materials for water remediation [1]. Although cellulose is mostly used in the form of fibers and nanofibers, it can also be utilized in the form of particles at the micro and nanoscales [2], exhibiting large surface area and abundant surface hydroxyl groups that enable a variety of physical and chemical modifications [3]. In the present study, cellulose-based beads incorporating magnetic and catalytic nanoparticles (NPs) were developed for enhanced water treatment applications. The cellulose beads from wood pulp fibers were produced using a dual-fluid system, with one hemisphere functionalized with magnetite (Fe3O4) NPs and the other with platinum (Pt) NPs. Scanning electron microscopy (SEM) confirmed their spherical shape and the two distinct surface topographies. Additionally, the resulting beads exhibited magnetic properties, auto-propulsion, and the potential to reduce the levels of organic pollutants, such as Rhodamine B. This dual-functional material presents a promising approach for advanced water treatment by combining magnetic and catalytic properties to enhance pollutant removal.
