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 …

The field of surface science provides a unique approach to understanding bulk, surface and
interfacial phenomena occurring during TiO 2 photocatalysis. This review highlights, from a …

TiO2 photocatalysts have been widely used in the field of renewable energy and
environmental clean-up. However, the large band gap of TiO2, along with the fast …

Driven by growing concerns for environmental and energy issues, interest in semiconductor-
based heterogeneous photocatalysis has increased considerably over the last decades …

In photoelectrochemical cells, sunlight may be converted into chemical energy by splitting
water into hydrogen and oxygen molecules. Hematite (α-Fe2O3) is a promising photoanode …

Defect states in reduced and n-type doped titania are of fundamental importance in several
technologically important applications. Still, the exact nature of these states, often referred to …

The formations of intrinsic n-type defects, that is, oxygen vacancies and titanium interstitials,
in rutile and anatase TiO2 have been compared using GGA+ U calculations. In both crystal …

The removal of lattice O atoms, as well as the addition of interstitial H atoms, in TiO 2 is
known to cause the reduction in the material and the formation of “Ti 3+” ions. By means of …

A visible-light-responsive photoelectrochemical (PEC) sensor was proposed for the
sensitive and selective analysis of chlorpyrifos (CPF) by synergistically using CoS 2 …

Many recent articles have suggested that density functional theory (DFT) with the
generalized-gradient approximation does not provide the correct electronic structure for the …
