and methyl orange (MO) with negative charge was investigated in TiO2 and Y2O3/TiO2 nanopowder suspension irradiated by high-pressure mercury lamp. As a result, the addition of Y2O3 to TiO2......
recycling experiment. The results show that removal rate of tetracycline is 98.13% under the conditions of 15 mmol/L H2O2, 0.50 g/L catalyst dosage, initial pH 3.0, 11 W UV lamp power and 60 min......
photocatalysts irradiated by 250 W high-pressure mercury lamp. The results show Ce-TiO2 coating on kieselguhr. The crystalline phase of titanium dioxide is still only anatase in wide range......
of fluorescent lamp. The results indicate that Pr and N co-doping efficiently restrains the growth of TiO2 crystalline size. The adsorption edge of visible light is red shifted, the phosphorescence......
of samples. Zr-N co-doped TiO2 has higher photo-catalysis activity than TiO2 under a 250 W high pressure mercury lamp and the degradation efficiency of methyl orange for 2% Zr-N co-doped TiO2 has a 32......
as content of hydroxyl radicals. The best removal rate of methylene blue solution (20 mg/L) reaches 93.86% under Haloid lamp of 250 W after 3 h with the nitrogen dosage of 0.15% (mass fraction), increase......
+ phosphor may have potential application for the red lamp phosphor.关键词:......
, and heat insulation, which remains constant under burning on an alcohol lamp and presents low thermal conductivity of 115.19 mW(m·K), close to the requirement for heat insulation. Synergistic effect......
of poly vinypyrrolidone (PVP) and irradiation of fluorescent lamp. The formation mechanism of silver nanostructure was proposed. The results show that both the PVP and the light irradiation are the keys... nanoparticles with compact aggregates to be adsorbed on the surface of glass substrates after irradiation of silanized quartz glass substrates attached with gold seeds smaller than 10 nm by a fluorescent lamp......
). The photocatalytic oxidation activity of the photocatalysts was also evaluated by the photodegradation of methyl orange (MO) in aqueous solution under visible light irradiation from a LED lamp (λ>400 nm..., and the residual MO concentration was (136±8) mg/L. The solution was irradiated by an 18 W-LED lamp from top with surface aeration by air flow of 0.6 L/min to obtain a uniform distribution of MO......
