Hierarchical Nanomaterials: Smart Microcapsules Encapsulating Reconfigurable Carbon Nanotube Cores (Adv. Funct. Mater. 5/2010)
Heavy metal ion removal is demonstrated using carbon nanotubes (CNTs) surrounded by iron oxide microcapsules by W. S. Choi on page 820. The CNTs conglomerate and form a core inside the capsule upon exposure to high temperature, while they scatter when they are subjected to mild sonication. These hierarchical structures can capture lead and chromium ions, which can later be desorbed by exposure to low pH conditions.
