Simulated Solar Irradiation

Simulated solar irradiation of wool, silk, bovine serum albumin and apomyoglobin in the presence of radioactively labelled fluorescent whitening agents of the bistriazinylaminostilbene and pyrazoline types results in the irreversible binding of radioactivity to the protein. This photochemical reaction occurs both in the solid state and in aqueous solution, and is believed to result in the formation of a covalent bond between the whitener (or a photodecomposition product) and the protein.

Simulated Solar Irradiation

GdVO4 was synthesized by solid state reaction at high temperature and characterized by XRD, UVvisible DRS, BET and SEM. XRD analysis of GdVO4 showed its structure was of tetragonal type. When GdVO4 was loaded with 0.3 wt% Pt, it showed the better photocatalytic activity for water splitting under simulated solar irradiation, and the amounts of the produced hydrogen in pure water were about 9.33 μmol under the irradiation of simulated solar for 6 h. Furthermore, photodegradation of Rhodamine B (Rh B ) on the samples were investigated under simulated solar irradiation.

Simulated Solar Irradiation

Copper doped graphene-TiO2 nanocomposite were prepared via sol-gel process and embedded onto ITO coated glass films using electrophoretic deposition technique. The catalyst films were used for photoelectrocatalysis (PEC) of CO2 induced under simulated solar irradiation. Triethanolamine (TEA) aqueous solution was used as an electrolyte in this experiment. CO2 capture in the electrolyte solution plays vital role in the PEC process and in this case, the effect of TEA was investigated. Although the absorption rate of CO2 is lower in TEA solution than primary or secondary amines, CO2 loading was found higher in the solution. Less reactivity of TEA towards CO2 was also observed. The impedance results showed that, increased concentration of TEA in aqueous solution helps to reduce charge transfer resistance and thus facilitates CO2 reduction process.
