One‐dimensional TiO2 Nanotube Photocatalysts for Solar Water Splitting

Hydrogen production from water splitting by photo/photoelectron-catalytic process is a promising route to solve both fossil fuel depletion and environmental pollution at the same time. Titanium dioxide (TiO2) nanotubes have attracted much interest due to their large specific surface area and highly ordered structure, which has led to promising potential applications in photocatalytic degradatio...

Plasmon-enhanced water splitting on TiO2-passivated GaP photocatalysts.

Integrating plasmon resonant nanostructures with photocatalytic semiconductors shows great promise for high efficiency photocatalytic water splitting. However, the electrochemical instability of most III-V semiconductors severely limits their applicability in photocatalysis. In this work, we passivate p-type GaP with a thin layer of n-type TiO2 using atomic layer deposition. The TiO2 passivatio...

Supersonic aerosol-deposited TiO2 photoelectrodes for photoelectrochemical solar water splitting

Photoelectrochemical (PEC) water-splitting is a promising approach for economical and environmentally friendly hydrogen production. We report here the preparation of nanocrystalline TiO2 films by aerosol deposition (AD) and their performance as photoelectrodes for PEC water splitting. The AD deposited films, 0.5 to 4 mm in thickness, were analyzed to establish the dependence of water splitting ...

Solar water splitting cells.

Energy harvested directly from sunlight offers a desirable approach toward fulfilling, with minimal environmental impact, the need for clean energy. Solar energy is a decentralized and inexhaustible natural resource, with the magnitude of the available solar power striking the earth’s surface at any one instant equal to 130 million 500 MW power plants.1 However, several important goals need to ...
