Heterogeneous photocatalysis has been identified as a means of using renewable solar energy to produce the sustainable, non-carbon fuel H 2 and a variety of useful chemical intermediates. Currently, however, heterogeneous photocatalytic reactions are too inefficient to be indust…

Nanotubes (inner diameter of 8nm and outer diameter of 10nm with a length of up to several hundred nm) and nanowires (diameter 20 – 50nm and up to several μm in length) of TiO₂-B have been synthesised and characterised for the first time. These exhibit excellent properties as a …
Carbon nanotubes (CNTs) are cylindrical structures of hexagonally bonded carbon atoms with diameters of a few nanometers. CNTs are generated with different structures characterized by their diameter and chirality (twist). Two types of semiconducting CNTs are zigzag (chirality &t…
Nanoporous anodic aluminum oxide (AAO) has vast implications as a tool for nanoscience research and as a nanostructure in which nanoscale devices can be fabricated because of its regular and ordered nanopores. Self-assembly plays a critical role in pore ordering, causing nanopor…
