1-D TIO2 NANOSTRUCTURES FOR PHOTOELECTROCHEMICAL

Popis výsledku v původním jazyce

With increasing demand on energy supply, necessity of the use of an efficient renewable source of energy is growing. One of the possibilities is conversion of solar light to electricity or fuel. Since the photocatalytic water splitting on TiO2 was discovered by Fujishima and Honda, the great effort has been devoted to application of TiO2 in solar light conversion. Although TiO2 is a suitable candidate for water splitting, some main drawbacks have to be overcome, such as high electron-hole recombination or short excited state life time. Using 1-D nanostructures (nanotubes, nanorods, nanowires or nanofibers) seems to be one of the possible ways how to increase the TiO2 effectivity. However, the use of TiO2 nanostructures is limited by utilization of only UV light irradiation, so the modification of the TiO2 with metal and/or non-metal ion doping to narrow the bandgap or sensitization by quantum dots or plasmon enhancement is necessary. 1-D nanostructures can be prepared by many different methods. Nanorods (NR) are commonly prepared by hydrothermal synthesis, oblique-angle deposition or metal-organic chemical vapour deposition; nanowires (NW) or nanofibers (NF) by hydrothermal synthesis, electrospinning method and hydrothermal corrosion of Ti metal substrate and nanotubes (NT) by anodization of Ti substrates or Ti thin layers, by template synthesis or hydrothermal synthesis.
