“…From the XPS spectra of Bi 4f, the peaks at 157.0 and 162.3 eV can been ascribed to Bi 4f 7/2 and Bi 4f 5/2 of Bi 3+ in QF-Bi 2 O 3 (Fig.3f) and QF-Bi 2 SiO 5 (Fig.3i), respectively. Regarding pure Bi 2 O 3 , the binding energies of Bi 4f 7/2 and Bi 4f 5/2 are 156.8 and 162.1 eV, respectively (Fig.S3h, ESI †) 34,35. The XRD and XPS results suggest that the Bi 2 SiO 5 formed in the surface of the integrated filler after sintering QF and Bi 2 O 3 .Similar morphologies of QF-Bi 2 O 3 and QF-Bi 2 SiO 5 were observed in the TEM images and the SEM images and XRD patterns.…”

“…Figure 11 a shows the photocurrent responses curves (PC) of PT and LST. Generally, a higher photocurrent density denotes a higher separation efficiency of photogenerated charges [ 46 , 47 ]. Both PT and LST generated photocurrent under light, and the photocurrent density of LST was higher than that of PT, indicating that Sn and La co-doping was beneficial to improve the separation efficiency of carriers.…”

Anatase/rutile heterojunctions were prepared using the sol–gel method and modified by La/Sn single doping and co-doping. Sn doping promoted the transformation from anatase to rutile, while La doping inhibited the phase transformation. La and Sn co-doping showed an inhibitory effect. The co-doping of La and Sn did not increase visible-light absorption, but exhibited a synergistic effect on inhibiting the recombination of photogenerated electrons and holes, which improved the photocatalytic activity on the basis of single-element modification. The first-order reaction rate constant of La/Sn co-doped sample was 0.027 min−1, which is 1.8 times higher than that of pure TiO2 (0.015 min−1). Meanwhile, the mechanism of photodegradation of methylene blue (MB) by La/Sn co-doped anatase/rutile heterojunctions was discussed through electrochemical measurements and free-radical trapping experiments.

Photocatalytic degradation of harmful organic matter is a feasible and environmentally friendly method. Bi2WO6 has become a hotspot of photocatalysts because of its unique layered structure and visible light response. In the present study, Sn doping was adopted to modified Bi2WO6 by hydrothermal method. The Sn-doped Bi2WO6 photocatalysts were characterized by XRD, SEM, TEM, BET, XPS, PL, and DRS, respectively. The results show that Sn-doped Bi2WO6 shows three-dimensional (3D) flower-like morphology, which is composed of two-dimensional (2D) nanosheets. Sn4+ ions enter into the Bi2WO6 lattice, producing a degree of Bi2WO6 lattice distortion, which is in favor of reducing the recombination of photogenerated electrons and holes. Moreover, the specific surface area of Bi2WO6 is significantly increased after doping, which is beneficial to providing more active sites. The photocatalytic results show that 2%Sn-Bi2WO6 exhibits the highest photocatalytic activity. After 60 min of irradiation, the photocatalytic degradation degree of methylene blue (MB) increases from 80.6% for pure Bi2WO6 to 92.0% for 2%Sn-Bi2WO6. The first-order reaction rate constant of 2%Sn-Bi2WO6 is 0.030 min−1, which is 1.7 times than that of pure Bi2WO6.
