Polarons are quasiparticles that easily form in polarizable materials due to the coupling of
excess electrons or holes with ionic vibrations. These quasiparticles manifest themselves in …

Photocatalysis is a process of clean technology where solar energy is converted into useful
chemical reactions. There are confronted challenges and limitations when claiming the most …

Breaking the strong covalent O–H bond of an isolated H2O molecule is difficult, but it can be
largely facilitated when the H2O molecule is connected with others through hydrogen …

The remarkable achievement by Fujishima and Honda (1972) in the photo-electrochemical
water splitting results in the extensive use of TiO 2 nanomaterials for environmental …

Environmental pollution and destruction as well as the lack of sufficient clean and natural
energy resources are some of the most serious problems presently faced on a global scale …

The importance of singlet oxygen (1 O 2) in synthesis of fine chemicals, inactivation of
viruses and bacteria, degradation of pollutants, and photodynamic therapy has promoted the …

Titanium dioxide is a promising photocatalyst for water splitting, but it suffers from low visible
light activity due to its wide band gap. Doping can narrow the band gap of titanium dioxide; …

The generation of hydrogen and oxygen from the photocatalytic water splitting reaction
under visible light is a promisingly renewable and clean source for H 2 fuel. The transition …

Conspectus The transition from fossil fuels to renewable energy requires the development of
efficient and cost-effective energy storage technologies. A promising way forward is to …

TiO2 anatase plays a central role in energy and environmental research. A major bottleneck
toward developing artificial photosynthesis with TiO2 is that it only absorbs ultraviolet light …
