The nano-team led by Professor Zhou and Professor Hu in the Centre for Advanced Materials Joining (CAMJ) has developed a facile method to fabricate titanium dioxide (TiO2) nanowire membranes for water treatment and environment remediation. These free-standing membranes are assembled by entangled TiO2 nanowires, with a diameter of 20 nanometres and a length up to a few hundred micrometers. These materials effectively remove various industrial pollutants, and pharmaceuticals. They are also successful in disinfection of different bacteria and viruses for high quality drinking water. Their work was recently reported by Water Canada.
