Formation of hybrid WO3-TIO2 nanotube and its application to conserve the environment

A B S T R A C T Hydrogen could be a significant fuel of the future replacing fossil fuel, which causing a major treat to social and environmental problems, such as carbon emissions, energy security and local air pollution. However, our future will certainly not be based on a simple replacement of fossil fuels by hy drogen but making it available at cheaper cost for everyone to utilize it. This is possible if we could generate hydrogen on renewable basis using water splitting technology. The development of hybrid transition oxide (WO3-TiO2) nanotubes (HTON) that capable of producing hydrogen gases in a cleaner, more efficient and cost -effective way by using two natural resources (sunlight and water). HTON has a stable, high chemical and thermal stability, active at room temperature as well as have extended their light absorption spectrum towards visible region, which is responsive to both ultraviolet and visible illumination. The HTON could be served as an efficient photo-induced electrons acceptor to facile better charge carrier separation in splitting water. In conclusion, HTON catalyst is the cornerstones for sustainable energy economy to conserve the environment because it could generate hydrogen efficiently and inexpensively for humankind.
