Photocatalytic Activity of Hydrogenated TiO₂

ACS Applied Materials & Interfaces, 2013
Photocatalysis is a promising advanced water treatment technology, and recently the possibility of using hydrogenation to improve the photocatalytic efficiency of titanium dioxide has generated much research interest. Herein we report that the use of high-temperature hydrogenation to prepare black TiO2 primarily results in the formation of bulk defects

Why hydroxocobalamin is photocatalytically active?

Chemical Physics Letters, 2012
Abstract Time-dependent density functional theory (TD-DFT) has been applied to investigate the relevant excited states involved in the photodissociation of hydroxocobalamin (HOCbl). The TD-DFT/BP86/6-31G(d) and TD-DFT/BP86/6-311G(d,p)//BP86-631G(d) calculations suggest that the photoscission of Co–OH bond is mediated by the repulsive 1(n + dCo → σ∗Co–

Photocatalytic activation of gypsum cements

Russian Journal of Applied Chemistry, 2017
Photocatalytic activity of gypsum cements that are based on the building plaster blend and synthetic calcium sulfate and contain 2–10 wt % titanium dioxide of anatase modification was studied. The decomposition rate of the model contaminant (Rhodamine C) on the surface of a plaster blend containing 2 wt %TiO2 becomes seven times higher under exposure ...

Chemical Auxiliary for Photocatalytic Active Colloids

Journal of the American Chemical Society
Active colloids with the ability to self-propel and collectively organize are emerging as indispensable elements in microrobotics and soft matter physics. For chemically powered colloids, their activity is often induced by gradients of chemical species in the particle's vicinity.
