About this deal
investigated the photodegradation of acid blue 92 and acid black 1 using SrSnO 3 as the photocatalyst and obtained discoloration percentages larger than 93%. The UV-vis spectra and the discoloration percentages of the dye solution after adsorption and photocatalytic tests at pH 6 and 3 are presented in Fig.
For the eco-conscious, bamboo bottles offer a sustainable option, and tech-savvy users can opt for smart bottles that track hydration. Espectro no infravermelho médio da amostra de CaSnO 3, calcinada a 800 ºC, obtido em KBr (inserto: espectro no infravermelho distante, da mesma amostra).
evaluated the use CaSnO 3 with microcube morphology for the photodegradation of rhodamine B, methyl orange and 4-hydroxyazobenzene dyes and observed high photocatalytic efficiency. Well-known chemicals may additionally be known via multiple generic, historical, commercial, and/or (black)-market names. We recommend that you do not fill carbonated drinks in the bottle (overpressure may damage the bottle). Characterization: the structure of the CaSnO 3 sample was evaluated by X-ray diffraction (XRD) using a diffractometer (XRD-6000, Shimadzu) operating at 40 kV and 40 mA with CuKα radiation.
UV-visible spectroscopy analysis was carried out using a UV-vis spectrophotometer (UV-2550, Shimadzu) scanned in the range between 190-900 nm in diffuse reflectance mode. Frequently these are arcane and constructed according to regional naming conventions relating to chemical formulae, structures or origins.performed a harmonic analysis of CaSnO 3 and presented the phonon density of states (PDOS) to correlate the contribution of Ca 2+, Sn 4+ and O 2- movements (apical and equatorial) with the dislocation frequency (ν). Calcium stannate (CaSnO 3) powders with the distorted perovskite structure have been synthesized by solid state and the sol-gel methods and their electrochemical performance was compared. The constitution of the heterostructure in CaSnO 3/Ag 6Si 2O 7 not only improved the separation of carriers but also promoted the absorption in the visible region owing to a reduction in the optical bandgap.
