Photocatalytic Activity of Inorganic Sunscreens
Journal of Dispersion Science and Technology, 2001Some inorganic pigments are used as ingredients for sunscreens as they can absorb, reflect or scatter UV radiation. Titanium dioxide and zinc oxide, which are used for this purpose, are semiconductor oxides and show photocatalytic activity. As a consequence, they can promote transformation of organic molecules upon absorption of radiation.

Why hydroxocobalamin is photocatalytically active?
Chemical Physics Letters, 2012Abstract 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, 2017Photocatalytic 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 ...

Photocatalytic activity of CuInS2 and CuIn5S8
Electrochimica Acta, 1992Abstract The photocatalytic activity of CuInS 2 and CuIn 5 S 8 , prepared by chemical precipitation, for the hydrogen evolution from aqueous sulfite solution was investigated. The photocatalytic activity of CuIn 5 S 8 was about twice that of CuInS 2 and was improved remarkably by the addition of silver sulfide.

Guang pu xue yu guang pu fen xi = Guang pu, 2010
The photocatalytic activity of nano-TiO2 prepared by pyrolysis method and then by cooling-treatment in silicon oil and in air respectively was studied with methyl-orange solution as model waste water. The results show that the photocatalytic activity of both products is obvious with no great difference.
