In this study, a NaNbO3/CdS/NiS2 ternary composite photocatalyst containing no precious metals was successfully prepared by a simple hydrothermal method. The prepared ternary photocatalyst has a significant improvement in photocatalytic performance of hydrogen production from water splitting under visible light irradiation. The best sample NCN40% hydrogen production rate is 4.698 mmol g−1 h−1, which is about 24.7 times that of pure CdS sample. In addition, the stability of the composite catalyst in the long-term photocatalytic hydrogen production cycle is also improved. The reason for the enhanced hydrogen production performance may be the optimization of the microstructure of the catalyst and the reduction of photogenerated electron-hole recombination. The construction of multi-heterojunctions (NaNbO3-CdS, CdS–NiS2, and NaNbO3-NiS2) helps to reduce the recombination of carriers. Furthermore, the in-situ-formed NiS2 nanoparticles can serve as active sites for hydrogen evolution. All of these factors induced the improved photocatalytic activity of the as-prepared ternary photocatalyst.

To study the degradation of tetracycline by Bi2S3-based binary composite and ternary composite photocatalysts, Cu2O/Bi2S3 and NH2-UiO-66/BiOBr/Bi2S3 was successfully fabricated by the solvothermal method, which can effectively and stably degrade tetracycline (TC). The crystal structure, chemical composition, and microscopic morphology of the as-prepared sample were analysed by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The photocatalytic performance of the composite photocatalyst was estimated by degradation of TC under visible-light irradiation. The results showed that the removal ratio of TC by Cu2O/Bi2S3 and NH2-UiO-66/BiOBr/Bi2S3 are 95.2% and 93.2%, respectively. The photoelectric properties of the material were evaluated by PL and EIS analysis, and compared to Bi2S3, the overall visible light absorption capacity, as well as the separation and transfer rates of photogenerated carriers of the composites photocatalyst have been significantly improved. Both Cu2O/Bi2S3 and NH2-UiO-66/BiOBr/Bi2S3 can achieve a good photodegradation performance for TC, but the results of UV–vis DRS spectrum, Mott–Schottky curve, and free radical trapping experiments show that their photodegradation mechanism for TC is different. For Cu2O/Bi2S3, •O2 − and h+ are the main active species in the photocatalytic reaction process, among which •O2 − plays the most important role, but •OH has almost no effect, and for NH2-UiO-66/BiOBr/Bi2S3, the main active species are •OH and h+. The possible photocatalytic mechanisms for Cu2O/Bi2S3 and NH2-UiO-66/BiOBr/Bi2S3 are Z-scheme and double Z-schemes are proposed, respectively.

SnS2 based SnS2/rGO/g-C3N4 Z-scheme ternary nanocomposites for efficient visible light-driven photocatalytic activity

In this work, an one-step solvothermal synthesis method is used to prepare TiO2-reduced graphene oxide (RGO)-CuO/Fe2O3 ternary composite photocatalysts with TiO2 and CuO/Fe2O3 nanoparticles coated RGO, while the structures and photocatalytic performance of these synthesized ternary composite photocatalysts are studied. It is found that Cu2+ and Fe3+ are substituted for Ti4+ into the crystal lattice of anatase TiO2 in these prepared ternary composite photocatalysts. TiO2 and CuO/Fe2O3 nanoparticles are uniformly coated on the surface of RGO and closely contact with each other. The Cu/Fe doping has obviously improved the absorption ability on the visible light, and the bandgap of the ternary composite can be reduced. Under visible light irradiation, by increasing the Cu/Fe doping amount, the photocatalytic performance can be improved until the Cu and Fe contents reached 0.075 wt.% and 0.1 wt.%, respectively. The prepared products can be reused for eight cycles to degrade the methyl orange solution, and it retains over 93% photocatalytic efficiency.

Structural, optical, and photocatalytic properties of La3+ doped CeO2 nanospheres for enhanced photodegradation of tetracycline

Novel ternary nanocomposite photocatalysts based on g-C 3 N 4 /Bi 2 MoO 6 /TiO 2 nanotube were synthesized using simple solid combustion, hydrothermal and wetness impregnation methods. The structural and morphological properties of the synthesized photocatalysts were systematically characterized using powder X-ray diffraction (XRD), Fourier transform infrared spectroscopy and scanning electron microscopy (SEM). The crystal structure and phase purity of unitary, binary, and ternary photocatalysts were confirmed by XRD analysis. The SEM analysis reveals the tubular morphology of the TiO 2 nanotube, and the presence of Ti, C, N, Bi, Mo, O, C, and N in the ternary composites was confirmed by EDX analysis. The photocatalytic decolorization efficiency of the ternary composites was evaluated by monitoring the decolorization of reactive black 5 and methylene blue dyes under visible light and direct sunlight irradiation, and these ternary composites were compared with binary composites and unitary photocatalysts in terms of the decolorization efficiency. After five cycles of adsorption and decolorization reactions, it was confirmed that the ternary composite photocatalysts were highly stable and reusable. From the results, we conclude that ternary composites (g-C 3 N 4 /Bi 2 MoO 6 /TiO 2 nanotube) are efficient photocatalysts for the decolorization of dyes.
