A novel synergy of Er3+/Fe3+ co-doped porous Bi5O7I microspheres with enhanced photocatalytic activity under visible-light irradiation

Highly efficient photocatalytic degradation of methylene blue by P2ABSA-modified TiO2 nanocomposite due to the photosensitization synergetic effect of TiO2 and P2ABSA

“…13 However, this photocatalytic activity enhanced mechanism has not been studied. 14 The photocatalytic process of P2ABSA/TiO 2 involves a primary reaction that generates holes and electrons, and a secondary reaction that generates ROS. 15 Therefore, successfully establishing a quantitative estimate of the contributions of P2ABSA in these primary and secondary reactions is important.…”

Synthesis of Flowerlike g‐C3N4/BiOBr with Enhanced Visible Light Photocatalytic Activity for Dye Degradation

“…The characteristic peaks in the 1200–650 cm –1 region are the typical stretching modes of C–N heterocycles. The peak at 810 cm –1 (Figure d) shows that the 5 %g‐C 3 N 4 /BiOBr nanostructure has the (110) crystal face , . The out‐of‐plane vibrations of BiOBr can be assigned as the symmetric stretching vibration peak of the Bi–O band in the BiOBr structure.…”

Bi@Bi4Ti3O12/TiO2 films on glass with photocatalytic and self‐cleaning performance

“…Due to the visible light absorption performance, bismuth (Bi)‐based materials, such as BiOI, Bi 5 O 7 I, and (BiO) 2 CO 3 ‐BiO 2− x composites, have also been widely investigated in the scientific research. Among them, bismuth titanate, which is capable of degrading pollutants in water under full spectral irradiation or visible light irradiation, has attracted much attention in recent years, including refractive sillenite phase Bi 12 TiO 20 , dielectric pyrochlore phase Bi 2 Ti 2 O 7 and ferroelectric perovskite phase Bi 4 Ti 3 O 12 .…”
