CaMoO4/CaWO4 heterojunction micro/nanocomposites with interface defects for enhanced photocatalytic activity

Hexagonal Ferrite MFe12O19 (M=Sr, Ba, Cu, Ni, Pb) Based Photocatalysts: Photoluminescence, Photocatalysis and Applications

“…At the same time, a similar phenomenon has been observed in Gd doped barium hexaferrite [117,118]. Similar phenomena have been observed in other metal oxides and composites [119][120][121][122][123]. MFe12 O 19 -based photocatalysts have high magnetic properties, which makes its application in the field of photocatalysis has been unprecedented development.…”

Synthesis, characterization, and photocatalytic CO2 reduction evaluation of the CaWxMo1−xO4 (x = 0–1) solid solution

“…However, adding W 6+ species in the solid solution caused the apparition of two extra bands associated with Mo 5+ species. 60 Table 1 summarizes the area ratios of both species (Mo 6+ and Mo 5+ ) in the samples, and the largest Mo 5+ ratio is exhibited by the W 0.2 M 0.8 sample, decreasing proportionally to the increase in W 6+ concentration in the solid solution. In this context, the formation of this mixed-valence can be directly related to introducing W 6+ species into the crystalline structure of CaMoO 4 , and this ratio reduction is associated with the decrease in Mo species in the solid solution, in which the W ones are the majority.…”

Synthesis and Characterization of BaTiO3/TiO2 Heterojunction Photocatalyst for Novel Application in Photocatalytic Degradation of TBBPA under Simulated Sunlight Irradiation

“…This result confirms once again that the Eg value will not change after the heterojunction is formed between the two metal oxide semiconductor materials, but only the oxygen defect will be introduced. [17] Photocatalytic activity…”

“…Eventually hydroxyl radicals or superoxide radicals react with pollutants to form carbon dioxide, water, and other non-toxic oxidation intermediates. The detailed reaction formulas are shown in ( 9)- (17).…”
