PHOTODEGRADATION OF METHYLENE-BLUE - USING SOLAR LIGHT AND SEMICONDUCTOR (TIO2)
(Amer Chemical SocWashington, 1993)
Photocatalytic bleaching of aqueous malachite green solutions by UV-A and blue-light-illuminated TiO2 spherical nanoparticles modified with tungstophosphoric acid
(Elsevier Science, 2011-09-01)
Visible-light-responsive spherical TiO2 particles were prepared by the sol–gel method by adding urea as pore-forming agent and tungstophosphoric acid (TPA) in different ratios (20% and 30% w/w) and by annealing at 500 ◦C ...
Photocatalytic discoloration of aqueous Malachite Green solutions by UV-illuminated TiO2 nano-particles under air and nitrogen atmospheres: Effects of counter-ions and pH
(Royal Society of Chemistry, 2011-01)
Under air atmosphere, the photocatalytic discoloration of malachite green (MG) aqueous solutions (atriphenylmethane dye) in the presence of TiO2 and UV light followed an oxidative pathway, involving an N-demethylation ...
