Hierarchical self-assembly of polyphenolic functionalized magnetic superstructure for enhanced removal of organic dyes

Nanocomposites play critical roles in catalytic oxidation, wastewater treatment, and other chemical engineering fields. Therefore, the strategies to develop multifunctional nanocomposite systems through chemical synthesis, physical doping, and assembly have been explored. The existing challenges inc...
