Synthesis, characterizations and applications of some nanomaterials (TiO_2 and SiC nanostructured films, organized CNT structures, ZnO structures and CNT-blood platelet clusters)

摘要

TiO_2 nanostructured films have been synthesized by the hydrolysis of Ti[OCH(CH_3)_2]_4 as the precursor. These films have been utilized for the dissociation of phenol contaminant in water. Free-standing nanostructured film of silicon carbide (SiC) has been synthesized, employing a simple and new route of spray pyrolysis technique utilizing a slurry of Si in hexane. Another study is done on organized carbon nanotube (CNT) structures. These are made in the form of hollow cylinders (50 mm length, 4 mm diameter and 1.5 mm wall thickness). These CNT-based cylinders are made of conventional CNT and bamboo-shaped CNT. The filtrations of heavy hydrocarbons and E. coli bacteria from water have been carried out. In addition to this, ZnO nanostructures have also been studied. Another study concerns CNT-blood platelet clusters.
