“…The sample 3Fe 3 O 4 /Ag/BiVO 4 /sepiolite exhibits the lowest fluorescence intensity, indicating the lowest rate of electron‐hole recombination. This suggests that the sample possesses the highest capability for photo‐generated carrier separation and migration efficiency [29] . This observation is consistent with its subsequently demonstrated highest photo‐catalytic activity.…”

To increase specific surface area and light utilization of photo‐catalysts, a series of Fe3O4/Ag/BiVO4/sepiolite composites with different Fe3O4 contents were synthesized via co‐precipitation. The structure, composition, and optical properties of these composites were characterized using X‐ray diffraction (XRD), nitrogen adsorption and desorption (BET), UV‐Vis diffuse reflectance spectroscopy (UV‐Vis DRS), and fluorescence spectroscopy (PL). The photo‐catalytic activity of the composites was further evaluated using rhodamine B as a model for photo‐catalytic degradation. The results revealed that the composites with optimal Fe3O4 loading exhibited the narrowest bandgap width, approximately 2.13 eV, and the highest electron‐hole pair separation efficiency. Rhodamine B could be almost completely degraded within a short illumination time in the presence of the Fe3O4/Ag/BiVO4/sepiolite composites. The degradation mechanism of rhodamine B was proposed to involve the improvement of the photo‐catalytic activity of the resulting composites by the Fe3O4 and the Z‐type heterojunction structure. Additionally, the composites could be recycled and reused multiple times, making them an environmentally friendly and sustainable option.

To study the influence of the construction of heterojunction on the visible-light response range and the photo-generated charge carriers separation efficiency of TiO2, two dimensional/three dimensional (2D/3D) ZnIn2S4/TiO2 heterojunctions were synthesized by high-temperature calcination followed by a facile oil bath method, and were investigated for the photodegradation of Rhodamine B (RhB) and tetracycline (TC). X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) were applied to investigate the composition, crystal structure, and morphology of the as-prepared specimens. UV-visible diffuse reflectance spectra (UV-vis DRS), electrochemical impedance spectroscopy (EIS), photocurrent measurement, photoluminescence (PL) spectra, and first-principles calculation were also performed to investigate the photoelectric property. The results showed TiO2 maintains the morphology of metal-organic frameworks (MOFs) with narrow visible-light response range and high photo-generated charge recombination efficiency. After coupling with ZnIn2S4 nanosheets, a larger specific surface area was obtained with offering more active sites for photocatalytic reaction. The band gap of the composite was reduced from 3.23 eV of TiO2 to 2.52 eV of ZnIn2S4/TiO2-II, and thus obtaining an extended visible-light response range and enhancing visible light utilization rate. The energy band structure acquired from the UV-vis DRS and XPS valence band spectra indicated a construction of type II heterojunction in the ZnIn2S4/TiO2 composite, and thus improving the separation and transfer efficiency of photo-generated carrier pairs, which was confirmed by the PL, EIS and photocurrent test results. Under the visible light, ZnIn2S4/TiO2 displayed significantly enhanced photocatalytic activity than bare TiO2 and ZnIn2S4. Among of ZnIn2S4/TiO2 photocatalysts, ZnIn2S4/TiO2-II possessed the highest photocatalytic degradation efficiency (93%) of RhB solution within 60 min, which was nearly 18 and 2 times higher than pristine TiO2 and ZnIn2S4, respectively. Besides, the ZnIn2S4/TiO2-II photocatalyst also showed enhanced photocatalytic activity for TC degradation than pure TiO2 and ZnIn2S4. The cycle experiment showed that the ZnIn2S4/TiO2-II photocatalyst could maintain good reusability, and it could still photodegrade 83% RhB after 5-cycle test. This work demonstrates that constructing 2D/3D ZnIn2S4/TiO2 heterojunction based on MOFs-derived TiO2 is an efficient strategy for significantly enhancing the photocatalytic activity of TiO2.
