Product Information

However, poor conductivity, intense carrier recombination, and low absorption in the visible range prevent them from being practical. An interpretation of the influence of pH on photocatalytic degradation must be performed considering the semiconductor surface charge, substrate nature and •OH production, which also changes at different pH values 40 40 U. The photocatalytic efficiencies of the photocatalysts were calculated by calibration curves; the initial absorption of the untreated dye solution and the respective concentrations before and after photocatalytic treatment were considered. Whether for domestic use, educational environments, professional settings, or physical activities, the versatility of these bottles caters to a broad audience.

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. Thus, this study aimed to synthesize CaSnO 3 by the modified Pechini method and evaluate the azo dye photodegradation under different conditions. In spite of this, a comparison with the results of the adsorption test indicated that a noticeable improvement in the activity occurred after UV irradiation, with a discoloration increase of 320%.

A high activity in the degradation of organic pollutants has been reported for alkaline earth stannates as a consequence of their dielectric semiconductor properties 9 9 P.According to literature, bands at this region are assigned to the ligand metal charge transfer (LMCT) O 2- n Sn 4+ for ions in an octahedral sites (28). g. the element chromium has 7440-47-3, the trivalent Cr(III) has 16065-83-1 and the hexavalent Cr(VI) species have 18540-29-9. The employed catalyst retained excellent recycling ability up to four cycles suggesting its excellent practicality in the field of catalysts. This behavior, associated with the CaSnO 3 large band gap, may decrease the possibility of electron-hole recombination reactions.
