Titania Nanotubes

New titania nanotubes findings from University of Michigan described

Published in Biotech Business Week, July 5th, 2010

"A major challenge to the use of photoelectrochemical cells for the production of hydrogen from water and solar energy is the low photoanode efficiency. These low efficiencies are largely due to losses associated with the recombination of the charge carriers and low photocatalytic activities," scientists in the United States report.

"In this work, two strategies were investigated for improving the photoanode performance: producing the semiconducting oxide (TiO2) in the form of long nanotube arrays and incorporating gold nanoparticles onto the surface. Highly ordered TiO2 nanotube (TiNT) arrays were fabricated using an anodization process. By varying the conditions,...
