Effective Visible Light-Activated B-Doped and B,N-Codoped TiO2 Photocatalysts
Su-Il In,Alexander Orlov,Regina Berg,Felipe García,Sergio Pedrosa-Jimenez,Mintcho S. Tikhov,Dominic S. Wright,Richard M. Lambert +7 more
TL;DR: A simple low cost method permits controlled, reproducible doping of TiO2 anatase by boron and the resulting materials exhibit red-shifted absorption spectra and unprecedented photocatalytic activity under visible light.
Journal ArticleDOI
New insights into the origin of visible light photocatalytic activity of nitrogen-doped and oxygen-deficient anatase TiO2.
TL;DR: These ab initio calculations reveal that the optical absorption of nitrogen-doped TiO2 in the visible light region is primarily located between 400 and 500 nm, while that of oxygen-deficientTiO2 is mainly above 500 nm.
Journal ArticleDOI
Photocatalytic Properties of TiO2 Modified with Gold Nanoparticles in the Degradation of 4-Chlorophenol in Aqueous Solution
TL;DR: In this article, the degradation in aqueous solution of 4-chlorophenol photocatalyzed by band-gap-irradiated TiO2 modified with nanoscopic gold particles was studied as a function of Au particle size by means of HREM, DRIFTS, BET, and reactor measurements.
Journal ArticleDOI
In situ and ex situ spectroscopic monitoring of biochar's surface functional groups
TL;DR: In this paper, the authors used FTIR spectral features at respective temperatures during in situ pyrolysis of lignocellulosic feedstock matched the peak temperature of post-production analysis.
Journal ArticleDOI
Reduction of NO2 to nitrous acid on illuminated titanium dioxide aerosol surfaces: implications for photocatalysis and atmospheric chemistry.
TL;DR: TiO2, a component of atmospheric mineral aerosol, catalyses the reduction of NO2 to nitrous acid (HONO) when present as an aerosol and illuminated with near UV light under conditions pertinent to the troposphere.
