Preparation, characterization of Au (or Pt)-loaded titania nanotubes and their photocatalytic activities for degradation of methyl orange

Synthesis of TiO2 nanotubes by using combination of sonication and hydrothermal treatment and their photocatalytic activity for hydrogen evolution

“…This lowered total energy and hence TiO 2 NT was formed (Chen and Mao, 2007). Similar results have been reported by Bavykin et al, (2004), Zhao et al, (2009), andPoudel et al, (2005), but essentially contradicting with the assumptions of Kasuga et al, (1999). They revealed an acid washing treatment step following the hydrothermal process to form tri-titanate nanotubes.…”

Advances in Photoelectrochemical Fuel Cell Research

“…TiO2 nanotubes have active photo catalysis characteristic, good corrosion resistance, thermal stability and good operation stability as described by Mahajan V et al, (2008). TiO2 nanotubes can be made by various ways including hydro/solvothermal method (Kasuga T et al, 1998), template-assisted approach (carbon nanotube, alumina or monocrystal as the template), sol-gel method (Kasuga T et al, 1998), microwave irradiation (Zhao Q et al, 2009), and direct electrochemical anodization. The advantage of the hydro/solvothermal method is easy to operate.…”

Preparation of TiO2 Nanoparticle/Nanotube Composites via a Vapor Hydrolysis Method and Their Photocatalytic Activities

“…But the TNTs obtained in this method are covered with a layer of SiO 2 and the photocatalytic reaction is restricted to the inside of nanotubes, which limit the further application of the nanotubes. On the other hand, the photocatalytic modification of TNTs has also been reported, including ZnO-supported [14], Au (Pt)-doped [15,16], and PbS surface coated nanotubes [7]. These composites still have some shortcomings in applications, such as the photocorrosion of ZnO or the high cost of the precious metals.…”
