“…Considering that visible light energy accounts for about 45% of sunlight energy [ 37 ], subsequently, in order to broaden the light-harvesting range, remarkable efforts have been devoted to explore visible light-activated semiconductors including CdSe, CdS, SiC, WO 3 , Fe 2 O 3 , Co 3 O 4 , g–C 3 N 4 , CdO, Ag 2 O et al as photocatalysts, which possess a narrow band gap that is less than or equal to 3.0 eV. Recently, bismuth-based (Bi-based) semiconductors with advantages of non-toxicity, low cost and good thermal stability and as new and important visible light-activated semiconductors have become a research hotspot [ 20 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 ]. Bi-based semiconductors usually refer to the Bi 3+ containing semiconductors because of the higher stability of Bi 3+ than Bi 5+ .…”

Recently, the bismuth-based (Bi-based) Z-scheme photocatalysts have been paid great attention due to their good solar energy utilization capacity, the high separation rate of their photogenerated hole-electron pairs, and strong redox ability. They are considerably more promising materials than single semiconductors for alleviating the energy crisis and environmental deterioration by efficiently utilizing sunlight to motivate various photocatalytic reactions for energy production and pollutant removal. In this review, the traits and recent research progress of Bi-based semiconductors and recent achievements in the synthesis methods of Bi-based direct Z-scheme heterojunction photocatalysts are explored. The recent photocatalytic applications development of Bi-based Z-scheme heterojunction photocatalysts in environmental pollutants removal and detection, water splitting, CO2 reduction, and air (NOx) purification are also described concisely. The challenges and future perspective in the studies of Bi-based Z-scheme heterojunction photocatalysts are discussed and summarized in the conclusion of this mini review.

“…In order to improve the pollutant degradation ability, BiVO 4 can be modied. For example, Ag/ BiVO 4 , 10 Cu/BiVO 4 , 11 AgI/BiVO 4 , 12 BiFeO 3 /BiVO 4 , 13 RGO/BiVO 4 , 14 Bi 12 TiO 20 /BiVO 4 , 15 Ag@AgVO 3 /BiVO 4 16 and PDA/g-C 3 N 4 / BiVO 4 17 ternary systems and binary systems have been reported. Nevertheless, the modied BiVO 4 has some disadvantages, such as small specic surface area, poor adsorption capacity and easy precipitation.…”

“…The interplanar distances of samples CTZ0 and CTZ3 were estimated by HR-TEM, and lattice fringes in multiple orientations so obtained are the confirmation of polycrystallinity of heterogeneous nanocomposites. This can be due to mismatching of lattice parameters [47] of ZnO, CdO, and TiO 2 , as can be seen from Figure 3c,d and Table 1.…”

Here, heterogeneous ternary metal oxide CdO:TiO 2 :ZnO (coded as CTZ0, CTZ1, CTZ2, CTZ3, CTZ4) nanocomposites are synthesized by a sol-gel precipitation method for the advanced oxidation process (AOP) under visible light. The structure, texture, and surface morphology of heterogeneous nanocomposites are identified by X-ray diffraction, high-resolution transmission electron microscopy, and field emission scanning electron microscopy, respectively, while the optical property is investigated by UV-vis spectrophotometry. Furthermore, mixed phases such as anatase and rutile TiO 2 , cubic CdO and hexagonal ZnO, as well as a mixture of morphology, viz., nanorod, nanoflakes, cluster, and aggregation of particles are observed concurrently for sample CTZ3. The reflectance of heterogeneous CdO:TiO 2 :ZnO nanocomposites is recorded in the visible wavelength range from 400 to 800 nm and optical bandgap is varied from 1.91 to 2.20 eV for samples CTZ1-CTZ4. The effect of weight load 5 g L −1 of heterogeneous nanocomposites is evaluated for degradation of organic dyes at neutral pH and obtains the highest efficiency for sample CTZ3 as 99.6% and 99.4% in methyl orange and methylene blue, respectively. Both biological oxygen demand and chemical oxygen demand values are reduced followed by AOP increasing the number of pollutant molecules for absorption in the mixture.
